(b) When nitric acid reacts with magnesium metal, magnesium nitrate and a gas is formed.(i) Describe a test to confirm the identity of this gas.test.. Introduce a lighted splint.observation...The gas will extinguish a lighted splint with a 'pop' sound.[2](ii) When magnesium metal...
After the metal sample has been dissolved in nitric acid (or the salt in water) and the pH adjusted to 8.1–9 (except for preconcentration of Hg, when pH 3 is used), the solution is filtered through a 2-cm paper coated with 50 mg of activated carbon. The trace metals are ...
The reaction between nitric acid and magnesium metal is one way and reaction with MgO is another. Magnesium hydroxide and ammonium nitrate also form the product but ammonia is released as a by-product: 2HNO3 + Mg Mg(NO3)2 +H2 2HNO3 + MgO Mg(NO3)2 +H2O Mg(OH)2 + 2NH4NO3 Mg(NO3)...

Magnesium, the lightest structural metal, is difficult to form at room temperature due to an insufficient number of deformation modes imposed by its hexagonal structure and a strong texture developed during thermomechanical processes. Although appropriat
