Question

Identify the statement which is not correct regarding $CuS{O}_4$

• A. It reacts with $KI$ to give iodine
• B. It reacts with $KCl$ to give $C{u}_{2}C{l}_2$
• C. It reacts with $NaOH$ and glucose to give $C{u}_{2}O$
• D. It gives $CuO$ on strong heating in air

Answer 1

Answer: (B)

$CuS{O}_4$ reacts with $KI$ to give white precipitate of $C{u}_2{I}_2$ and to evolve $I_2.$ But it does not react with $KCl$ in the same way.
