A 0.100 M solution of K2SO4 would contain the same total ion concentration as which of the following solutions?
A. 0.0800 M Na2CO3
B. 0.100 M NaCl
C. 0.0750 M Na3PO4
D. 0.0500 M NaOH

    K2SO4 split when it ionizes as follows:
    K2SO4(aq) ==> 2K^+ + SO4^2- or a total of three ions for each mol K2SO4. The concn in the problem for K2SO4 is 0.1 so the total concn of ions = 0.3M

    Go through the answers and see which is larger.
    Na2SO4 = 3 ions x 0.08 = 2.4M ions
    NaCl = 2 ions x 0.1 = 0.2 M ion.
    etc.
