a)
\(CH_3COOH⇌CH_3COO^-+H^+\)
\(H_2O⇌OH^-+H^+\)
MK: \(CH_3COOH,H_2O\RightarrowĐKP:\left[H^+\right]=\left[CH_3COO^-\right]+\left[OH^-\right]\)
b)
\(HNO_3\rightarrow H^++NO_3^-\)
\(NaHSO_4\rightarrow Na^++HSO_4^-\)
\(HSO_4^-⇌H^++SO_4^{2-}\)
\(H_2O⇌OH^-+H^+\)
MK: \(KOH,HSO_4^-,H_2O\RightarrowĐKP:\left[H^+\right]=\left[NO_3^-\right]+\left[SO_4^{2-}\right]+\left[OH^-\right]\)
c)
\(KOH\rightarrow K^++OH^-\\ H_2O⇌OH^-+H^+\\ NH_3+H^+⇌NH_4^+\)
\(MK:KOH,NH_3,H_2O\RightarrowĐKP:\left[H^+\right]=\left[OH^-\right]-\left[NH_4^+\right]-\left[K^+\right]\)
