Physical Chemistry Laboratory Experiment II-6b solubility , IONIC STRENGTH AND ACTIVITY COEFFICIENTS . References: 1. See `References to Experiments' for text references. 2. W. C. Wise and C. W. Davies, J. Chem. Soc., 273 (1938), "The Conductivity of Calcium Iodate and its solubility in Salt Solutions". Background: Study the references to the text and the section on "Theory and Discussion" carefully. Know the definitions of the following and their interrelations: ACTIVITY a, ion ACTIVITY , ai, mean IONIC ACTIVITY , a . ACTIVITY coefficient, , ion ACTIVITY coefficient, i, mean IONIC ACTIVITY coefficient, . solubility , S in moles per liter solubility product constant in terms of (a) molarity, K and (b) ACTIVITY , Ks. IONIC STRENGTH , I. Debye-Huckel Theory expressions, "Limiting Law" and "Detailed Law". How solubility data are used to evaluate Ks?
How solubility data are used to evaluate K s? Balanced Redox reactions used to determine IO 3-concentration. Objectives: Measurement of solubility of a sparingly soluble salt, such as calcium iodate in KCl solutions of various ionic strengths. Determination of the …
