Sorption of alkali by wool from aqueous solutions of sodium carbonate and bicarbonate has been examined by measurement of hydrogen‐ion concentrations. The effects of concentration of alkaline salt, time of immersion, liquor ratio, and temperature of equilibration have been studied in relation to subsequent measurement of the pH of an aqueous extract of a treated sample. A qualitative interpretation of results is given, and a quantitative treatment employing the Donnan theory of membrane equilibria has been attempted.
