Explanation:
The above two reactions xcan also be written in form of single chemcial equation:
1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.
2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.
3. On mixing, KSCN with we will get blood red color solution of .
