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.
