3. The maximum amount of manganese(II) carbonate that will dissolve in a 0.280 M sodium carbonate solution is
M.

NO need to explain long , just short answer :) ty

Answer 1

1)

Ksp of Ag3PO4 = 1.3 x 10^-20

Ag3PO4 (s) -------------> 3 Ag+   +   PO43-

                                         0.252           S

Ksp = [Ag+]^3[PO43-]

1.3 x 10^-20 = (0.252)^3 x S

S = 8.12 x 10^-19

molar solubility = 8.12 x 10^-19 M

2)

Ksp of Mg(OH)2 = 1.5 x 10^-11

Mg(OH)2   --------------> Mg2+ (aq) + 2 OH- (aq)

                                      0.201               2 S

Ksp = [Mg2+][OH-]^2

1.5 x 10^-11 = 0.201 x (2S)^2

S = 4.32 x 10^-6 M

maximum amount = 4.32 x 10^-6 M

3)

MnCO3   -------------> Mn2+   +   CO32-

Ksp = [Mn2+][CO32-]

1.8 x 10^-11 = s x 0.280

S = 6.43 x 10^-11

maximum amount = 6.43 x 10^-11 M
