Would a precipitate be observed if equal volumes of a 0.040 m agno3 solution and a 0.030 m nano2 solution are mixed?

    When we have equals volumes of AgNO3 & NaNO2 so we can assume that the total volume = 1 L

    so we need to new concentrations of:

    [Ag+] = 0.04/2 = 0.02 M

    and [NO2-] = 0.03 / 2 = 0.015 M

    So we need to get Q expression to compare it with the KsP value

    when Q = [Ag+][NO2-]

    by substitution:

    Q = 0.02 * 0.015 = 0.0003

    ∴Q = 3 x 10^-4 by comparing this value with Ksp = 6 x 10^-4 (missing in your queston)

    ∴Q
    and when Q < Ksp this means that, this is an unsaturated solution and there is no precipitate will be observed.
