QUESTIONS 1. There is a solution contains both Ag* and Cu²+ ions. It is desired to be separated these ions by precipitation. What needs to be done to separate these two cations from each other? 2. A cation in a solution is precipitated by addition of an anion containing solution (reagent). Precipitate dissolves when more of the same reagent is added onto the precipitate. Explain this event by writing an example reaction. 3. What is aqua regia acid solution? Explain it briefly. 4. Thioacetamide can be used instead of H2S gas. Explain the reason by writing the relevant reaction/s.

A sample of solid calcium hydroxide, Ca(OH)2, is allowed to stand in water until a saturated solution is formed. A titration of 75.00 mL of this solution with 5.00102M HCl requires 36.6 mL of the acid to reach the end point. Ca(OH)2(aq)+2HCl(aq)CaCl2(aq)+2H2O(l) What is the molarity?
Jake was given an unknown solution thought to contain Pb²⁺ and/or Ba²⁺ and asked to perform chemical tests to identify each ion in solution. To begin, Jake added a solution containing sulphate ions to the solution and a precipitate formed. Jake concluded that the precipitate must be barium sulphate, proving the solution contained Ba²⁺ ions. What is incorrect about Jakes reasoning? Explain what Jake could have done differently?
