Question

1. Balance the following reaction under basic conditions

_O3+_I-+_H2O = _O2+_I2+_OH-

2. How many grams of ozone gas are needed to react with 45.00 mL of a 0.200 M aqueous solution of KI according to the chemical equation shown above?

3. What is the concentration (in mol/L) of OH- at the end of the reaction?

Answer 1

first OXIDATION HALF REACTION is balanced

then REDUCTION HALF REACTION IS balanced

then both equation are added

and final equation is automatically get balanced

it is a type of redox reaction

for simplicity i have shown reduction processes in two step
