Consider the four weak acids listed below.
Which would exist primarily as a cation in an aqueous solution with pH =1.4\%
glyoxylic acid, K_{a} = 6.6 * 10 ^ - 4 p*K_{a} = 3.2
propanoic acid, K_{a} = 1.4 * 10 ^ - 5 p*K_{a} = 4.9
) alloxanic acid, K_{a} = 2.3 * 10 ^ - 7 p*K_{a} = 6.6
all would be cationic
none would be cationic
malonic acid, K_{a} = 1.5 * 10 ^ - 3 p*K_{a} = 2.8
