Problem K3 D

Postby Jasmin Argueta 1K » Thu Feb 28, 2019 7:13 pm

Hi everyone, just wondering if anyone can explain why in the redox reaction cl2---> HCLO+Cl2 the cl2 goes from cl2+2electrons--->2Cl- , in particular where does the minus come from that allows you to know to add the electrons to the left side?

Cl2 on the right side currently has a charge of zero. Since it is reduced to Cl- on the right side, the electrons must be on the left to balance the charge. It is 2 electrons since there must be 2 Cl - on the right side to balance the equation.

I was confused about this too. Is it possible that there's a typo in the book? I feel like it should be this:
cl2---> HCLO+2Cl-

It seems weird to have cl2 on both sides of the equation.
