Calculate the concentration of ions in the following saturated solutions.

(a) [I −] in AgI solution with [Ag+] = 8.1 10-9 M

(b) [Al3+] in Al(OH)3 solution with [OH −] = 1.8 10-9 M

  • Chemistry - ,

    AgI ==> Ag^+ + I^-

    Ksp = ? = (Ag^+)(I^-)
    Substitute Ksp and Ag^+ and solve for I^-

    In b don't forget to cube the OH^-
