Reaction of alkaline earth metal With nitric (V) acid.

Answer Text:
Reaction of alkaline earth metal With nitric (V) acid.
Beryllium:
- When a piece of beryllium is dropped into a beaker containing nitric (V) acid, there is effervescence of a colourless gas.
- The colourless gas produces a pop sound when exposed to a burning splint confirming that it is hydrogen gas.
- A colourless solution of beryllium nitrate remains in the test tube // boiling tube.
Equation: #Be(s) + 2HNO_3(aq) → Be(NO_3)_2(aq) + H_2(g)#
Magnesium:
- When a piece of magnesium is dropped into a beaker containing nitric (V) acid, there is effervescence of a colourless gas.
- The colourless gas produces a pop sound when exposed to a burning splint confirming that it is hydrogen gas.
- A colourless solution of magnesium nitrate remains in the test tube // boiling tube.
Equation: #Mg(s) + 2HNO_3(aq) → Mg(NO_3)_2(aq) + H_2(g)#
Calcium:
- When a piece of calcium is dropped into a beaker containing nitric (V) acid, there is slight effervescence of a colourless gas.
- The colourless gas produces a pop sound when exposed to a burning splint confirming that it is hydrogen gas.
- A colourless solution of calcium nitrate remains in the test tube // boiling tube.
Equation: #Ca(s) + 2HNO_3(aq) → Ca(NO_3)_2(aq) + H_2(g)#
