How to write equations for salt dissolving in water/ionizing

  1. Jan 2, 2017 #1
    1. The problem statement, all variables and given/known data
    Write separate equations for each potassium salt (KH2PO4) dissolving in water and for the ionization reaction of the weak acid anion that each of these salts contains.

    2. Relevant equations

    None
    3. The attempt at a solution
    I just needed to clarify when it dissolves in water do I include that in reaction or just do a dissociation of the ion? Furthermore, for ionization reaction of weak anion, it is H2PO4, so what does this mean?

    There is no strict rule to the first step (and I would have no problems if the first step was omitted, but your instructor can have a different opinion).

    H2PO4- can dissociate. Actually it can also hydrolyze. Both reactions have to be listed.
