Logarithmic measure of acid strength derived from KaK_aKa
pKa=−log10KapK_a = -\log_{10} K_apKa=−log10Ka
Ka=10−pKaK_a = 10^{-pK_a}Ka=10−pKa
[HA]initial≈[HA]equilibrium[\text{HA}]_{\text{initial}} \approx [\text{HA}]_{\text{equilibrium}}[HA]initial≈[HA]equilibrium
[H+]=Ka×[HA]initial[\text{H}^+] = \sqrt{K_a \times [\text{HA}]_{\text{initial}}}[H+]=Ka×[HA]initial
