Question

In obtaining copper sulfate from $Cu$,sulfuric acid acts as:

• A. reducing agent
• B. oxidising agent
• C. promoter
• D. inhibitor

Answer 1

Answer: (B)

oxidising agent

In obtaining copper sulfate from $Cu$ sulphuric acid act as oxidising agent which reduce copper from zero oxidation state to $C{u}^{+2}$:

$Cu\left(g\right)+H_{2}S{O}_4\left(l\right)\to CuS{O}_4\left(aq\right)+S{O}_2\left(g\right)+2H_{2}O\left(l\right)$
