1-A solution is known to contain either Cu2+ ion, Bi3+ ion, or both ions. Describe a single test that would identify the ion(s) present. State what would be observed if (a) both ions were present, (b) if only Cu2+ ion was present, (c) if only Bi3+ ion was present.procedure that would allow the determination of which ion is present. What would youexpect in each step?
would determine which ion is present. Explain what you would expect in each case.4-The experimental procedure presented in this experiment was used to analyze a solution containing Bi3+, Cu2+, Cd2+, and Sn4+ ions. For each of the following changed in the procedure, predict the effect on the separation of the involved cations:(a) The Group II precipitation was done at a pH 0.0 instead of pH 0.5.(b) The Group II precipitation was done at a pH 5.0 instead of pH 0.5.
