For A⁻ + H₂O ⇌ HA + OH⁻, Kb = Kw/Ka = (1.0 \times 10^-14 / 1.8 \times 10^-5 = 5.56 \times 10^-10)
Reaction: ( HCl + NaOH \rightarrow NaCl + H_2O ) (1:1 ratio) titrasi asam basa contoh soal
[OH⁻] = (\sqrtK_b \times C = \sqrt(5.56 \times 10^-10)(0.0500)) = (\sqrt2.78 \times 10^-11 = 5.27 \times 10^-6 , M) For A⁻ + H₂O ⇌ HA + OH⁻, Kb = Kw/Ka = (1
