Ammonia dissolves in water to form ammonium hydoxide, not a meetallic ion in sight!
Alkaline
OH- ions are present in excess in alkaline solution
Ammonia react with water molecules. By that OH- are made
Metallic
Sodium Bicarbonate is considered as acidic due to H+ ion. The formula is HCo3. Please remember when HCo3 dissolves the H+ ionizes and imparts acidity to alkaline solution.

Most likely copper.
it because of the ammonium ion form in the solution. Ammonium solution is an alkaline.
Metallic
Sodium Bicarbonate is considered as acidic due to H+ ion. The formula is HCo3. Please remember when HCo3 dissolves the H+ ionizes and imparts acidity to alkaline solution.
Both are Cupric ( Cu-II ) alkaline complex-ion solutions
alkali metals
The metallic ion in this case is Na+, or sodium. If there is a metal ion in a chemical formula, it will be the one written at the beginning.
when pH of a solution is in the range of 7-14, the solution is said to be alkaline solution.
Ammonium sulfate is a neutral salt which shows alkaline behavior in solution due to the hydrolysis of the ammonium ion.
