    I've been stumped by one of the solubility questions on AAMC practice test #3. If there is a sequential precipitation reaction such as the following:

    A + B = C (precipitate)

    C + D = E (precipitate)

    E + F = G (precipitate)

    -does this mean that compound G is less soluble than E which is less soluble than C? If so why?

    Are you asking about transitivity?

    Let me rephrase this, is compound G less soluble than E IF/GIVEN E is less soluble than C?
    Note: The solubility of a compound is only relative to the substance that it reacts with.
