    1. The problem statement, all variables and given/known data
    Calculate the pAg after the addition of 5ml, 40ml, and 45ml of 0.05M AgNO3 to 50.00ml of 0.04M Kbr (AgBr Ksp = 5 x 10^-13)


    2. Relevant equations



    3. The attempt at a solution
    when 5ml of AgNo3 is added , we have
    (50 x 0.004 - 5 x 0.05)/55
    = 0.0318
    P(kbr) = -log 0.0318
    = 1.497

    The point is that I dont know when and how to calculate the Pag. I find this topic very confusing.I will be very gratefull if anyone can give me a hint on how to solve this problem. Thanks

    What is the definition of pAg?

    PAg means the P-function of Ag.

    So what do you need to calculate pAg? (note the capitalization - pAg, not PAg, just like pH and not PH).
