You are watching: Copper oxide and sulfuric acid reaction
Ores containing cupric oxide, CuO, are commonly reacted v sulfuric mountain to develop a copper containing product that is much more easily processed. This procedure is well-known as sulfuric mountain leaching. Compose a balanced chemical equation because that the reaction the cupric oxide through sulfuric acid.
Cupric oxide is one more name for copper(II) oxide. Cupric is provided to show a compound whereby copper is in the plus two oxidation state. Because that reference, Cu⁺ is indicated by words cuprous. Sulfuric acid, meanwhile, is a solution of H₂SO₄ in water. Therefore what we’re feather at below is the reaction that copper(II) oxide through sulfuric acid. Top top the roadway to our well balanced chemical equation, composing the formula because that cupric oxide is the an initial step. The next reactor is sulfuric acid. And also the question we have to ask ourselves is, What space the products?
Cupric oxide is a metal oxide, and sulfuric acid is an acid. The intended outcome from such a reaction is a metal salt add to water. As soon as sulfuric mountain is used, we suppose the salt to be a sulfate. This is because when sulfuric mountain reacts v a metal oxide, the will provide up two H+ ions, leave behind the SO four two minus anion. You deserve to see how the sulfuric acid and also the sulfate have actually these atom in common. Therefore, the salt we intend is copper sulfate. We know the formula for copper(II) sulfate is CuSO₄ because the two confident charge that the copper ion counterbalances perfect that two minus charge of the sulfate anion.
Now, every we need to do is inspect that that balanced. There’s one identical of copper top top the reactant side and also the product side, two equivalents the hydrogen on both sides, one equivalent of sulfur on both sides, and also five equivalents that oxygen on both sides. The equation is, therefore, balanced. So because that the reaction that cupric oxide with sulfuric acid, the balanced chemical equation is CuO add to H₂SO₄ reaction to type CuSO₄ plus H₂O.
What is the name of the copper include compound created when cupric oxide reacts through sulfuric acid?
for this question, we deserve to simply go ago to words equation. We understand that sulfuric acids react to produce sulfates, and also the cupric describes copper(II). So our products are copper(II) sulfate and water. For this reason the name offered to the copper-containing compound produced when cupric oxide reacts through sulfuric mountain is copper(II) sulfate. Alternatively, you might substitute copper(II) for cupric and cupric sulfate. Or you can use its common name, copper sulfate, where it is assumed the copper is in that most common oxidation state, add to two.
What is the key reason for sulfuric acid leaching that cupric oxide ores? A) The product the the reaction is an ext soluble than cupric oxide. B) The product of the reaction has a lower melting allude than cupric oxide. C) The product of the reaction is less toxic than cupric oxide. D) The product the the reaction is much less stable than cupric oxide so it deserve to be electrolyzed an ext easily. Or E) The product of the reaction develops smaller crystals than cupric oxide for this reason it can be ground up more easily.
right here we’ve been given five possible reasons because that sulfuric acid leaching. Remember that the main reason because that doing every this is since we desire to attain pure copper at the end. For this reason sulfuric acid leaching takes united state partway indigenous copper oxide to a systems of copper sulfate. Copper oxide is insoluble solid, when a systems of copper sulfate is liquid. This renders it much easier to convert the problem to pure copper. The systems is blended with various other chemicals that enable it to it is in reduced. Grind up the pure ore, which would possibly have actually other contaminants in it as well, would certainly be much much less effective. The main reason for sulfuric mountain leaching is to develop this systems of copper sulfate. This highlights alternative A. The product the the reaction is much more soluble 보다 cupric oxide as the finest answer. But I’m going come look v the various other answers just in case.
The second statement states that the product the the reaction has actually a lower melting suggest than cupric oxide. After ~ sulfuric acid leaching, the product is no melted. Copper is no reactive enough to react v water and, therefore, have the right to undergo systems phase reactions and also does not must be purified through electrolysis. Therefore, this is not the factor for sulfuric acid leaching. The 3rd statement is that the product that the reaction is less toxic than cupric oxide. The truth of the matter is the both cupric oxide and copper sulfate are toxic. The copper sulfate created is conveniently converted right into other things. So even if it is or not it’s less toxic is no really an issue. Therefore, this, too, is no a exactly answer.
The fourth option claims that the product that the reaction is much less stable 보다 cupric oxide so it might be electrolyzed an ext easily. The stability of a salt is not as essential as the solubility as soon as it concerns solution electrolysis. So even if the equipment would be electrolyzed, the security of the salt would certainly not it is in an issue.
Now, we have the right to move on come the last statement. The last feasible reason is that the product of the reaction creates smaller crystals than cupric oxide so it can be soil up more easily. The product in question, copper sulfate solution, is preserved as a solution. This way, it deserve to be much more easily introduced to the other processing steps. Therefore, that does not must be floor up. So whether it’s less complicated or harder does not really matter. Therefore, this is an incorrect answer. Therefore the exactly answer because that the main reason because that sulfuric mountain leaching of cupric oxide ores is that the product that the reaction is an ext soluble than cupric oxide.
To acquire metallic copper, the product of sulfuric acid leaching is reacted with one more elemental metal. Through considering their family member costs and reactivities, recognize which the the adhering to metals is most an ideal for usage in this reaction. A) Lead. B) Silver. C) Sodium. D) Aluminium. Or E) Iron.
simply for reference, recall that the product of sulfuric acid leaching is a equipment of copper sulfate. To start off v this question, ns going come look at the reactivities the the metals involved. What we want to achieve here is the reduction of copper(II) to add ions. The steel is supposed to react with the copper(II) ions in solution and also turn them into copper metal. In the process, these steel atoms are going to form metal ions of your own. For this come occur, the steel must be an ext reactive than copper. Command is greater up the reactivity series than copper. Therefore, it’s capable of displacing copper ion from solution. Silver- is much less reactive than copper. Therefore, that is incapable of participating in this reaction. So silver is certainly not a correct answer.
salt looks promising to begin with since it is much more reactive than copper. Unfortunately, sodium reacts v water rather violently. A equipment of copper sulfate is mainly water. So sodium would react v the water prior to it reacts with a copper sulfate and also would be highly ineffective and also dangerous come use. Therefore, it is no a exactly answer. Meanwhile, aluminium above copper in the reactivity collection is not so far over that it react so violently with water. Therefore, it’s quiet a candidate. Iron, too, is much more reactive than copper, so will be effective in displacing copper ion from solution.
The 2nd factor in the concern is cost. Ideally, we’re looking for the metal that is the least expensive. We’ve currently eliminated silver. Yet we can be double sure around eliminating it because it is very expensive. Lead and aluminium are relatively cheap. Aluminium is produced by electrolysis, i m sorry raises the price a little. However, it’s developed on very big quantities, allowing for economies of scale. Meanwhile, sodium, likewise produced through electrolysis, is a bit more of a niche product. So it’s less cheap 보다 aluminium. Iron, on the various other hand, is the most renowned metal top top the planet. Favor lead, it’s produced in a blast furnace, but on much, much bigger scales.
This renders iron the ideal candidate based on relative cost and reactivity. If you’re interested, below are the present prices in mass for every of the metals. Together you have the right to see, stole is the cheapest, v sodium at about twice the price and also silver at about 370 time the price. The expenses of lead and also aluminium are on the same order of magnitude as the expense of iron.

Therefore we can be i was sure that, based on relative cost and reactivity, iron is the ideal candidate the end of these 5 metals for use in this reaction.
