Problem is KClO3 + HBr > Br2 + H2O + KCl
What are the oxidation and reduction reactions that take place before balancing?
Thanks!

Oxidation is loss and reduction is gain. Oil Rig.
Writing the first reaction out, you get :
Potassium chlorate is gaining electrons. This is the reduction half reaction.
Bromide is losing electrons. Therefore, this is the oxidation half reaction.
The overall reaction :
Writing the first reaction out, you get :
Code: Select all
6H+ + KClO3 + 6e- --> KCl + 3 H2O
Code: Select all
3(2Br- --> Br2 + 2e-)
The overall reaction :
Code: Select all
6 HBr + KClO3 --> 3 H2O + KCl
