How can i calculate the solbilty of silver chloride?

  1. Apr 27, 2013 #1
    1. The problem statement, all variables and given/known data

    Ksp of silver chloride is 1.8x10-10 mol2dm-6 at RTP

    a) calculate the solubility of silver chloride in gdm-3 in
    i) pure water
    ii) in 0.1M silver nitrate solution

    b)Is silver chloride more soluble in water of in a solution containing silver ions. Why?
    c) Why is silver chloride more soluble in aquouse ammonia than in water?


    2. Relevant equations

    AgCl = Ag+ x Cl-


    3. The attempt at a solution

    Ksp = [Ag+] x [Cl-]
    1.8x10-10 = S x S

    S= √1.8x10-10

    Which i find the solubility. How do i convert it to g dm-3?

    b)?
    c)?

    What units will your solubility be in?

    Before answering b try to solve a ii. c refers to additional reaction that takes place in the ammonia solution.

    mol/dm3

    Well, you know how many moles of AgCl dissolve in a liter of water. Just convert from moles of AgCl to grams of AgCl and realize that a liter is the same volume as a cubic decimeter.
