Web% ionization is calculated as [Ac-]/ [HAc]+ [Ac-] X 100, so you must find [Ac-] since you know that the denominator = 0.0100 M. In the expression for Ka, assume that [H+] = [Ac-] = x, and [HAc] = 0.0100-x. Because Ka is small, assume that x will be small compared to 0.01 and can be ignored. Then, x = [Ac-] = 4.20X10^-4 M Reply a year ago Follow
