When H\(_2\)S is passed into a solution of iron (III) chloride, the solution turns
-
Pale green
- Pale red
- Brown
- Colourless
The correct answer is: A
Explanation
A reaction between Iron (iii) chloride and Hydrogen sulphide leads to the reaction
2FeCl\(_3\)(aq) + H\(_2\)S(g) → 2FeCl\(_2\)(aq) + 2HCl(aq) + S(s)
The colour change is from REDDISH BROWN to PALE GREEN.
