WebAug 8, 2024 · pH = 4.10 Explanation: If it was a strong acid then the concentration of H + that dissociates from N aH 2P O4 would be 2 ×0.1 = 0.2M But N aH 2P O4 is a weak acid. It will dissociated partially. If x represents concentration of acid that dissociates then x = √Ka × C (see Ernest answer for more details about this formula) WebIf a buffer solution contains 1.0 M HCN H C N (pKa = 9.3) and 0.1 M CN − C N −, what is the pH of this solution?
