Can u help me in balancing the following eqn. through oxidation no. method or half reaction method.
Also please show and explain the steps.

HNO3(aq.) + KI(aq.) -----> NO(g) + I2(s)+ H2O(l) + KNO3(aq.)
Hoping for a quicker response.

I goes from -1 to 0
N goes from +5 to +2

There must be three I for each N that is changed.

so... 2NO and 3I2 would be a starting point.

check my thinking.

Hey mr. Bobpursley, I didn't get ur answer clearly.Can u please explain me in proper steps.i tried to balance from ur hint but coudnt do that.

I showed you the change in oxidation steps, and that there must be three changes of I for each change of N. Then I put the final coefficents in those producets to balance. The rest is for you.
