Question

What is the pH of a solution of 0.600M KH2PO4, potassium dihydrogen phosphate?

Answer 1

you need to know the Ka's of the 2nd proton and 3rd proton

Answer 2

then write the dissociation equations. and find [H+] for each, then add them together

then pH=-log[H+]


in reality [H+]=[H3O+] but it's easier with this simplification

Answer 3

You need to try and solve the problem yourself first before we can actually give you any sort of solution to your problem, heycoa. Sorry.
