The triprotic acid H3A has ionization constants of Ka1 = 9.9× 10–2, Ka2 = 2.7× 10–8, and Ka3 = 5.9× 10–11.
a). Calculate the following values for a 0.0570 M solution of NaH2A
H+ ??
[H2A^-/H3A]??
b). Calculate the following values for a 0.0570 M solution of Na2HA.
H+ ??
[HA^2-/H2A]??
they give you the formulas to solve for H+ but i've tried it so many times and it is still wrong..
