CHEM-PLEASE HELP

posted by on .

Calculate the molar solubility of silver chloride (AgCl) in:
a-deionized water and
b-.20M NaCl solution
Given Ksp=1.6*10^-10

  • CHEM-PLEASE HELP - ,

    .........AgCl ==> Ag^+ + Cl^-
    I........solid....0.......0
    C........-x.......x.......x
    E........solid....x.......x

    Ksp = 16E-10 =- (Ag^+)(Cl^-)
    Substitute and solve for x = (AgCl) in M.

    for part B. You need to calculate (or find in a table) the activity of 0.20M NaCl solution and recalculate the solubility using activities instead of molarity..
