Variation in specific conductance of Ca(OH)2 solution with temperature, dilution, and addition of Glycerol

Quick and accurate determination of Calcium hydroxide is needed by lime and pharmaceutical industries. It is a slightly soluble salt and its saturated aqueous solution shows anomalous behaviour with respect to temperature and conductance. Ca(OH)2 is completely soluble in Glycerol but the addition of Glycerol in the saturated aqueous solution of Ca(OH)2 quenches its conductance. The variation of conductance with dilution and temperature is measured for a wide range. Addition of glycerol in small aliquots is followed with the measurement of conductance. The experimental values put forth in this work would help to understand the properties of a saturated solution of Calcium hydroxide popularly called as “Lime water”
