is there a detailed table containing relation between H2SO4 conc.,PH / or H ion conc., and sulfate ion conc.?

Question

when using tow different types of PH calculator for constructing a table two different results appered. And by using MATLAB for solving the relation between acid conc. and H conc. for diprotic acid gave a new result some of it agrees with practical results and others not agree

Answer 1

You don't need tables. These concentrations are easy to calculate.

H2SO4 + 2H2O = 2H3O+ + SO4-

c(H3O+) = 2 × c(H2SO4)
c(SO4-) = c(H2SO4)
ph = log 2×c(H2SO4)

Practical results often differ from the theoretical ones. In theory all factors are perfect, whereas in practice they are not. For instance, ph does not only depent on the concentration of ions, but also on their activeness.
Not all quantities are calculable (yet), some just have to be measured.

Answer 2

They won't MATLAB uses in built heuristics for the prediction.
