In finding the pH of the solution containing amphiprotic salts, diluted solutions contain significantly lower molar concentration of the salts, resulting to negligible significance of Kw in the equation, thus [H3O'] is approximately equal to the square root of the first two acid dissociation constants. With this, calculate the hydronium ion concentration of a 0.100 M NaHCO3 solution, given that Kay = 1.5 x 104 and Kaz = 4.69 x 10¹" a. 8.4 x 10-8 M b. C. d. 8.1 x 10-¹0 M 8.5 x 10⁹ M 8.3 x 10-1¹ M
