Question

Will give medal and fan .

One is made by dissolving lithium carbonate (Ksp = 8.15 x 10-4) in 100.0 mL of water until excess solid is present, while the other is prepared by dissolving lithium phosphate (Ksp = 2.37 x 10-4) in 200.0 mL of water until excess solid is present. Which solution has a higher lithium cation concentration?

Answer 1

Li2CO3

8.15 * 10 ^ -4 = 4x^3
x = 0.0588
Li concentration : 0.1176

Li3PO4

2.37 * 10^-4 = (3x)^3 * x
x = cube root of ((2.37*10^-4) / 9 )
x = 0.0298
Concentration of Lithum = 0.089

BUT It is wrong the concentration of Li in Phostphate should be more than the first , where am I wrong ??? PLZ TELL .
