Please answer from b ii to c ii. Thank you.
2 Tal Define the thermodynamic solubility product, K, and the apparent solubility product, K, of an insoluble salt, AgCl, in its dissolving process shown below. Ksp = [Ag+][CI-] (2 marks) AgCl (s) Ag (aq) + CI" (aq). If AgCl is dissolved in pure water, its What is its K in terms of 5*? solubility is S-1.3x10 m. Ksp = S^2 (2 marks) Suppose an electrolyte is added to the solution, the solubility is changed to S, what is its Kap? Ksp = 1.69 x 10^-10 (2 marks) (iii) At low value I of added electrolyte, how does S change from S? (2 marks) (iv) At high value / of added electrolyte, how does S change from Sº ? (2 marks) 1½ Given: logy, AZ.Z 1+B (0) Define the van't Hoff factor, i, of an electrolyte. (4 marks) (ii) The osmotic pressure of a 0.01m solution of CaCl₂ and a 0.01m sucrose solution at 298 K are 0.605atm and 0.224atm, respectively. Calculate the van't Hoff factor and the degree dissociation for CaCl₂. Assume ideal behavior. (6 marks) (c)
