A solution of unknown group I ions gives a white precipitate with HCl.When treated with hot water, it gives a solution to which K2CrO4 is added, and a yellow precipitate forms.The white precipitate that remains after the hot water treatment dissolves completely in NH3. Which ions are present and which are not?
a. What cations may be present in a pale blue solution that turns deep blue and forms a white precipitate upon 6M NH3(aq)? b. A white solid dissolves in water to form a neutral solution. No precipitate forms when the solution is treated with a solution of NH4Cl/ NH3 buffer, nor when (NH4)2S is added. When the solution is acidified with HC2H3O2 and K2CrO4 is added a yellow precipitate forms. This precipitate dissolves upon addition of concentrated HCl. Acidification of a solution of the solid with HNO3 followed by addition of AgNO3 causes formation of a white precipitate. What is the identity of the original solid?
