Homework Statement
A saturated solution of iodine in water contains 0.330g of I2/L. More than this can dissolve in a KI solution because of the following equilibrium-
I2(aq) +I-(aq) ------> I3- (aq) where 2 and 3 are subscripts and - is negative charge
A 0.1M KI solution actually dissolves 12.5g of iodine/L, mmost of which is converted to I3-. Assuming that the concentration of I2 in all saturated solutions is same, calculate the equilibrium constant for the above reaction.
Homework Equations
The Attempt at a Solution
0.33g/L is 0.0013 mole and 12.5g/L is 0.0492 mole
I don't know how to proceed
