suggest a precipitation method for the separation of potassium ion from sodium and lithium ions
Homework Answers
Treatment of the solution contains high concentration of K+ with Na+ and Li+ with dilute perchloric acid will form KClO4 which is sparingly soluble in water and it will leave Na+ and Li+ in the solution. Filtration of the KClO4 precipitate will seperate the K+ ion from Na+ and Li+.

You wish to use precipitation to separate Br− ion from I− ions in a solution that is 0.50 M in each. You find Ksp values for the copper(I) salts are 6.3 x 10−9 for CuBr and 1.3 x 10−12 for CuI at 25°C. If you are required to reduce the value of one ion to 0.10% of its original value for “complete separation,” will selective precipitation by Cu+ work? Show your calculations and justify your answer.

An ammonium ion selective electrode exhibits interference from lithium ions with a selectivity coefficient of 0.2. If a 0.10 M solution of ammonium has an electrode potential of 0.125 V what is the expected potential in a solution containing both 0.1 M ammonium and 0.1 M lithium? Recall that the Nernst equation for a cation selective electrode with interferent is Ecell L'002 Logho(a + Kb) where a and b are the activities(-concentrations) of the selective ion and interfering ion, respectively.
