To a solution containing one ion at a known concentration is added a known volume of a solution containing a known concentration of the second ion. Agitation of the mixture and time allowance for complete equilibration of the saturated solution and precipitated solid is then performed. After equilibration the solid is allowed to settle or is centrifuged. Serious error at this stage can be avoided by forming the precipitate under conditions in which rapid coagulation is obtained (solutions in concentration range 0.01 to 2 M). After removal of the solid, the activity of 5 nfl of the supernatant liquid is compared with that of 5 ml of the original solution of concentration STAN/sup -/!/sub 0/. The solubility product for lead iodide was determined by the above titration method to be 0.88 plus or minus 0.20 x 10/sup -8/ at 18 deg in agreement with other experimental values. (C.J.G.)
