1.A solution may contain some of the soluble ions from group 1 but it does contain other cation or interferringsubstances. when 12 drops of 6 M Hydrochloric is added, no precipitate.
B. To a solution that is known to contain come of the soluble ions from group 1 and no other cations or inteferring substances, 12 drops of 6M hydrochloric acid is added and no precipoiate forms.To clear solution is evaporated to half its volume and 12 more drops of 6M hydrochloric acid is added followed by the addition of water until the solution's volume is 2mL. To this solution 1mLn of thioacetamide solution added and when the test tubeis heated, a dark brown precipitate forms?
