A saturated solution of iodine in water is 1.25 × 10 –3 (M). In any saturated solution of I 2 concentration of I 2 is 1.25 × 10 –3 (M). In 1 L of 0.1 (M) solution I – , it is seen 51.25 × 10 –3 mole of I 2 can be maximum dissolved. In the aqueous solution of I – (aq), I 2 (ag) undergoes complex formation, I 2 (aq) + I – 
(aq). What is the value of K C ?
A
750
B
800

Text Solution
Verified by ExpertsThe correct answer is:
B
I 2 + I – 
51.25 × 10 –3 0.1
At 1.25 × 10 –3 (M) 50 × 10 –3 (M) 50 × 10 –3 (M)
Equilibrium
K C = 
= 
= 800
