Answer to Question #193217 in Biochemistry for CLEMENT AGBESI

Question #193217

Calculate the salt to acid ratio ([Aˉ]/[HA]) of a solution of an amino acid at pH 2 and

pKa of 8.95

Expert's answer

"pH=pKa+log\\frac{[A^-]}{[HA]}"

"2=8.95+log\\frac{[A^-}{[HA]}"

"-6.95=log\\frac{[A^-]}{[HA]}"

"log\\frac{[A_]}{[HA]}=10^{-6.95}"
