Â Â a. Pb3(PO4)2 ----------> 3Pb⁺² + 2PO4^3-

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 3sÂ Â Â Â Â Â 2s

Â Â Â KspÂ Â Â Â Â Â Â Â Â Â = [Pb+2]³[PO4^3-]²

Â Â Â Â 1*10^-54Â Â Â = (3s)³ *(2s)²

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 108s⁵

s⁵Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 1*10^-54/108

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 0.0926*10^-55

sÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 4.5*10^-12 M

solubility of Pb3(PO4)2 is 4.5*10^-12 M

b.Â Â Â Â Â Â Â Â Â Â Â Hg2Br2 ---------> Hg₂²⁺ + 2Br^-

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 0Â Â Â Â Â Â Â Â Â Â 0.3

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â sÂ Â Â Â Â Â Â Â Â Â 0.3+2s

Â Â Â Â Â Â Â Â Â KspÂ Â Â = [Hg₂²⁺][Br-]²

Â Â Â Â Â Â Â Â Â Â 6.4*10^-23Â Â = s*(0.3+2s)²

Â Â Â Â Â Â Â Â Â Â Â Â Â sÂ Â Â Â Â Â Â Â Â Â Â Â = 1.4*10^-17

due to commom ion effect solubilities are different in water and inCaBr2.
