1.) Explain what you would do to prove that a solution contained lead(II) ion?
2.) You are given a white solid and told that it is either potassium nitrate or silver nitrate. Explain what you would do to determine the identity of the solid?
3.) You are told that an acid is either hydrochloric acid or nitric acid. What simple test could you carry out to tell which acid it is?
4.) You are given a solution and asked to determine which Group I cations are present in it. Addition of hydrochloric acid results in the formation of a precipitate. The precipitate is washed with hot deionized water. When the filtrate from hot water washing is tested with potassium chromate solution, a precipitate forms. When a solution of ammonia is added to the remaining precipitate from the addition of HCL, it completely dissolves. What do you conclude?
5.) A yellow solid is either lead(II) chromate or potassium chromate. What would you do to tell which compound the solid is?
