The answer is: Cl was reduced in this reaction

according to the balanced reaction equation, we can know that:

- as Cl in OCl^ - is + 1

and Cl in Cl^ - is - 1

- and Cr in CrO4^-2 is + 6

- and Cr in Cr (OH) 3 is + 3

∴ Cl went from + 1 to - 1 and was reduced, It means a reduction in charge.

& Cr went from + 3 to + 6 so it was oxidized.
