Which of the following ionic/molecular species does not disproportionate in water at room temperature?
Options
- AN O 2
- BC u +
- CM n O 4 2 -
- DCa(OCl)Cl
Correct answer
D. Ca(OCl)Cl
Step-by-step solution
Here only Ca(OCl)Cl does not disproportionate in water at room temperature. 2NO 2 + H 2 O → HNO 3 + HNO 2 → Disproportionation relation Room temp . HNO 3 + NO 2 C u ( a q ) + → R . T . C u + C u ( a q ) 2 + C a OCl C l → W a t e r C a 2 + aq + C l - aq + O C l - aq
