The concentrations of a saturated solution of I2 in water is 1.33 x 10^/3 M.
Also, I2 -------- I2(CCl4), K = [I2(CCl4)]/[I2(aq)] = 85.5
A 10.0-mL sample of saturated I2(aq) is shaken with 10.0 mL CCl4. After equilibrium is established, the two liquid layers are separated.
a.) What mass of I2, in mg, remains in the water layer?
b.) If the 10.0-mL water layer in (a) is extracted with a second 10.0-mL portion of CCl4, what will be the mass in mg of I2 remaining in the water?
c.) If the 10.0-mL sample of saturated I2(aq) had originally been extracted with 20.0 mL CCl4, would the mass of I2 remaining in the aqueous solution have been less then, equal to, or greater than in part (b)? Explain.
