How does nitric acid reacts with copper and zinc?

How does nitric acid reacts with copper and zinc?

Copper metal “dissolves” in nitric acid (HNO3). We have seen this reaction before in the copper chloride lab). [Cu(H2O)6]2+ (aq) + Zn (s) –> Cu (s) + Zn2+ (aq) + 6 H2O (aq) At the same time, some of the zinc metal, which is present in excess, reduces hydronium ions to H2.

What happen when copper react with nitric acid?

Talking about the reaction between copper and nitric acid, copper is oxidized by concentrated nitric acid to produce \[C{u^{2 + }}\] ions. The nitric acid is reduced to form nitrogen dioxide which is a poisonous brown gas with an irritating odour. Also, Cupric nitrate, \[Cu{(N{O_3})_2}\] is formed in this reaction.

Why does zinc not react with nitric acid?

Aluminum and zinc do not react with concentrated nitric acid since a thick, hard to dissolve oxidation layer builds (passive oxidation) that protects the metal against further assaults.

What gas is produced when copper sulfate and zinc react?

In Part E of the experiment, the zinc metal is added to undergo a redox reaction with the copper(II): Zn + Cu+2 → Cu + Zn+2 Hydrogen gas is also generated in this step.

What can you not mix with nitric acid?

Never mix concentrated nitric acid and organics, such as acetone, unless you are following a respectable procedure and use a blast shield and proper precautions.

What happens when zinc reacts with concentrated nitric acid?

Zinc reacts with concentrated Nitric acid to produce Zinc nitrate, nitrogen dioxide and water.

Why is zinc not very reactive?

The answer is that zinc is able to lose its outer electron more readily than copper. This phenomena occurs because copper metal is able to delocalize its outer electrons more readily than zinc.

What is the reaction between copper and zinc?

In the first reaction, the copper ion is able to oxidize the zinc metal. However, in the second reaction, the zinc ion is not able to oxidize the copper metal. Zinc is a better reducing agent than copper.

What is the balanced equation for zinc and copper sulfate?

Zinc + copper sulfate is an example of a single replacement reaction. Zinc is higher than copper on the electromotive series, so will react to displace the copper from copper sulfate. This reaction takes place in an aqueous solution. The balanced chemical reaction is Zn(s) + CuSO4(aq) → Cu(s) + ZnSO4.

What is the reaction of CuSO4?

When H2O is added to CuSO4, a simple reaction occurs resulting in the formation of copper sulfate pentahydrate (CuSO4.5H2O), which is also known as blue vitriol. Again Copper sulfate on dehydration loose the water molecule and forms copper sulfate monohydrate which is bluish white in color.
