The autoprotolysis constant, K hw , for heavy water, D 2 O, at 25C is 1.35 *
Question:
The autoprotolysis constant, Khw, for heavy water, D2O, at 25°C is 1.35 * 10–15.
(a) Write the chemical equation for the autoprotolysis (more precisely, the autodeuterolysis, because a deuteron is being transferred) of D2O.
(b) Evaluate pKhw for D2O at 25°C.
(c) Calculate the molar concentrations of D3O+ and OD2 in pure heavy water at 25°C.
(d) Evaluate the pD and pOD of heavy water at 25°C.
(e) Find the relation between pD, pOD, and pKhw.
