Assertion :On adding zinc pieces to aqueous $F e {C l}_{3}$ solution, colour changes from deep yellow to light green. Reason: Aqueous $F e {C l}_{3}$ is acidic and on adding $Z n$ nascent hydrogen is produced which reduces deep yellow $F e {C l}_{3}$ solution to light green $F e {C l}_{2}$ solution.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
