    1. The problem statement, all variables and given/known data
    I was asked to calculate the pH of .40M solution of NH4ClO4

    but I wasn't given a Ka for it.

    2. Relevant equations

    3. The attempt at a solution

    I dissciated NH4ClO4 into:

    NH4(plus) and ClO4(minus)

    but I"m stuck there. What am I doing wrong?

    So far OK. Determine which ion is responsible for pH change. There are pKa (Ka) tables - use them.
