Acid strength
pKa=−log10KapK_a = -\log_{10} K_apKa=−log10Ka
Ka=10−pKaK_a = 10^{-pK_a}Ka=10−pKa
Dissociation is minimal
[H+]=Ka×[HA][\text{H}^+] = \sqrt{K_a \times [\text{HA}]}[H+]=Ka×[HA]
4.74
1.35×10−31.35 \times 10^{-3}1.35×10−3 M
[H+]=10−pH[\text{H}^+] = 10^{-\text{pH}}[H+]=10−pH
pH=pKa\text{pH} = pK_apH=pKa
[HA]=[A−][\text{HA}] = [\text{A}^-][HA]=[A−]
