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 precipitate forms.To solid is separated from the solution by centrifugation.The 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 1mL of thioacetamide solution added and when the test tube is heated, no precipitate forms?
