In an acid solution, K₂ = [H3O*]. Consider 1.0 M acidic solutions of the imaginary acids, HA, HB and HC and the 1.0 M salt solutions NaA, NaB, and NaC. If HA has the lowest pH, then 1.0 M NaA would have the highest pH. Ka of an acid multiplied by the Kb of its conjugate base equals Kw. The stronger the base, the weaker its conjugate acid. None of these are true.arrow_forwardMonochloroacetic acid, HC2H,C1O,, is a skin irritant that is used in "chemical peels" intended to remove the top layer of dead skin from the face and ultimately improve the complexion.
