Temperature Dependence of the Solubility of a Sparingly Soluble Salt Abstract: This lab was performed in order to view the effect temperature has on the solubility of a salt solution that is not completely soluble. Ca(OH)2 was dissolved in water at two different temperatures in order to create a graph of the solubility vs the temperature. The van’t Hoff equation was rearranged to form a linear equation for temperature as the x value and the natural log of the K value as y. The equation was determined to be y = -1200.4x - 13.183. Introduction: The solubility of a solution depends on the temperature of a solution and the volume of the solution. To illustrate the effect of changing the temperature of the solution the salt Ca(OH)2 was dissolved in water at two different temperatures and then titrated to determine the amount of Ca(OH)2 that was dissolved. Ca(OH)2 is a salt. Salts are composed of two ionic compounds together and are usually completely dissociated when placed in water but due to the hydroxide which normally does not dissociate being combined with the Ca the salt is slightly soluble. The van’t Hoff equation will be used in
