The solubility (in mol/L) of silver chromate in 1.20 M in potassium chromate,  silver nitrate and in pure water is

  • X = 5.0*10^-7 M
  • X'' = 8.333*10^-13 M
  • X'''= 6.694*10^-5 M

This is further explained below

What is the solubility (in mol/L) of silver chromate in 1.20 M potassium chromate aqueous solution?

Generally,The Chemical reaction is

Ag2CrO4 <----> 2 Ag+ + CrO42-

Ksp = [Ag+]^2[CrO42-]

1.12×10−12 = [Ag+]^2[CrO42-]

Hence

1.12×10−12.=(2X)^2*(1.2)

X = 5.0*10^-7 M

b)

1.12×10−12=(1.2)^2*(X)

1.12×10−12= 1.44 * 1(X)^1

X'' = 8.333*10^-13 M

In conclusion

1.12×10−12=(2X)^2*(s)

1.12×10−12= 4(X)^3

X'''= 6.694*10^-5 M
