Question

What is the action of copper with dil. HCl and h2so4? Write the equation

Answer 1

Answer:

Cu + H2so4 =cuso4+2Hcl

Answer 2

There will be no action of copper with dil. HCl and $H_{2}SO_{4}$.

Explanation:

• According to the reactivity series, a more reactive element is able to displace a less reactive element in a chemical reaction. As copper is placed below hydrogen in the reactivity series therefore, copper is not able to displace hydrogen when it reacts with dilute HCl in a chemical reaction.

• Hence, the reaction $Cu + HCl \rightarrow CuCl_{2} + H_{2}$ does not occur as copper is less reactive than hydrogen.

• Similarly, $Cu + H_{2}SO_{4} \rightarrow CuSO_{4} + H_{2}$ does not occur as copper is less reactive than hydrogen.
