Q17 / 90 · JEE Main 2021 (20 Jul Shift 2) · Chemistry

${Cu}^{2 +}$ salt reacts with potassium iodide to give

Correct answer
A
${Cu}_{2} I_{2}$
B
${Cu}_{2} I_{3}$
C
$Cul$
D
$Cu {(I_{3})}_{2}$

Solution

$2 {Cu}^{+ 2} + 4 I^{-} ⟶ {Cu}_{2} I_{2} (s) + I_{2}$

$2 {Cu}^{+ 2} + 3 I^{-} ⟶ 2 CuI + I_{2}$

Hence, the correct answer is option: 'A'.
