Reacts with dilute HCl to produce CO2 gas. When added to MgSO4 solution it produces a white precipitate.
Reacts with dilute HCl to produce CO2 gas. When added to MgSO4 solution it produces a clear solution which turns white when heated.
Reacts with BaCl2 to produce a white precipitate. When dilute HCl is added to the precipitate, it does not dissolve.
Reacts with BaCl2 to produce a white precipitate. When dilute HCl is added to the precipitate, it dissolves.
Reacts with AgNO3 solution to produce a white precipitate. The precipitate dissolves when dilute NH3 is added.
Add cold FeSO4 solution, and a little concentrated H2SO4 slowly. A brown ring forms between the two layers.
Add ammonium molybdate reagent and warm to 40oC to produce a yellow precipitate. When NH3 solution is added, the precipitate dissolves.
