CNS^(-) ions give red colour with Fe^(3+...

`CNS^(-)` ions give red colour with `Fe^(3+)` ions in aqueous solution as:
`Fe^(3+)(aq)+3CNS^(-1)(aq)toFeunderset("red")((CNS))_(3)(aq)`
If 0.1 M KCNS solution is separated from `0.1 M FeCl_(3)` solution by means of semipermeable membrane, red colour will appear on:

A

`FeCl_(3)` solution

B

`KCNS` solution side

C

both sides

D

neither side

To solve the question regarding the appearance of red color when 0.1 M KCNS solution is separated from 0.1 M FeCl3 solution by a semipermeable membrane, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Reaction**: The reaction between `Fe^(3+)` ions and `CNS^(-)` ions forms a complex ion `Fe(CNS)₃`, which is responsible for the red color. The reaction can be represented as: \[ \text{Fe}^{3+}(aq) + 3 \text{CNS}^-(aq) \rightarrow \text{Fe(CNS)}_3(aq) \quad \text{(red color)} ...
