    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    A lewis acid donates a electron pair while a bronsted-lowry acid accepts a proton. So I need to cancel out all the ones that has proton exchanges. They are B, C, D and E. However, in A, it isn't really an acid base reaction but a solubility equation.

    In B the cyanide ion accepts a proton.
    In C the ammonia accepts a proton.
    In D the water accepts a proton
    In E the hydroxide accepts a proton.

    Clearly, one of these isn't true so where was my thinking wrong?
