Chemistry

Phathalic acid, H2C8H4O4, is a diprotic acid and has aconcentration of 2.9 M. Ka1 = 0.0012 and Ka2 = 3.9 x 10-6. Estimatethe concentration of [HC8H4O4-] and [C8H4O4-2] at equilibrium.Determine Kb1 and Kb2. Determine the pH of the solution at eachproton dissociation. 11. Calculate the molar solubility of calciumhydroxide (Ksp = 4.8 x 10^6

I NEED TO KNOW HOW DID THEY GET THIS ANSWER PLEASE 0.0012 =x2/2.9 x = 0.059 M equilibrium concentration of HC8H4O4- = 0.059M
