Formic acid ((HCOOH)) is a monoprotic acid that ionizes only partially in aqueous solutions. A (0.13 , M) formic acid solution is (3.7%) ionized. Assuming that the molarity and molality of the solution are the same, calculate the freezing point and the boiling point of (0.13 , M) formic acid.
(a) (-1.86° C, 101.86° C)
(b) (-2.34° C, 102.34° C)
(c) (-1.62° C, 101.62° C)
(d) (-2.01° C, 102.01° C)
