12. The following quantities of salts were added to a volume of water to make liter of solution x 10-moles NaCl 2 x 10-2moles CaCl2 2 x 10-2moles BaCl2 (a) What is the ionic strength of the solution? (b) A small amount of phosphate salt is added to the same solution with negligible change in ionic strength. Given K=10-72 for the reaction H2PO H HPO2 Calculate [HHPO1/H,PO. , called "K, using the Güntelberg ap proximation of the DeBye-Hückel law (c) Calculate the "salting-out" coefficient, k,, for a nonelectrolyte in the same solution if its activity is 10-3 M and its concentration is 9.5 x 10 M 12.
