Question
A saturated solution of I2 in water contains 0.33 g litre−1 of I2 more than this can be dissolved in a KI solution because of the following equilibrium:
I2+I−⇌I−3. A 0.1 M KI solution (0.1M I−) actually dissolves 12.5g/litre I2, most of which is converted to Assuming that the concentration of I2 in all saturated solution is the same, calculate the equilibrium constant (Kc) for the above reaction. What is the effect of adding water to clear saturated solution of I2 in KI solution.
