CuS O_4 reacts with KCN solution and forms: - Vidyadip

MCQ

$CuS{O_4}$ reacts with $KCN$ solution and forms:

✓
${K_3}[Cu{(CN)_4}]$
B
$Cu(CN)$
C
$Cu{(CN)_2}$
D
${K_4}[Cu{(CN)_6}]$

✓

Answer

Correct option: A.

${K_3}[Cu{(CN)_4}]$

a
(a) $CuS{O_4}$ on reaction with $KCN$ gives ${K_3}[Cu{(CN)_4}]$
$2CuS{O_4} + 10KCN \to 2{K_3}[Cu{(CN)_4}] + 2{K_2}S{O_4} + {(CN)_2}$
