Question

At pH 5.0, what is the conce en tration of OH^- in solution ______ If the monoproticacid HAb has. pK of 3 and a solution is adjusted topH 5: what is the concentration of hydrogen ions in that solution ____________ what is the ratio of Ab- toHAb_______ Oxalic acid, a di-protic, di-carboxylic acid has pKs of 1.3 and 4.3 and thus can exis H2o.., HOx and Ox (please us. the sam. in your answer). what would be the dominant form at pH 3.3 ______________ What would be the second most dominant from at pH 3.3 _______________

Explanation / Answer

1. given pH = 5

pOH = 14-pH = 14 - 5 =9

pOH = -log [OH-] = 9

log [OH-] = -9

[OH-] = 1 x 10^-9M
