Explain the following :
dilute nitric acid is generally considered a typical acid but not so in its reaction with metals.
Unlike other dilute acids only very dilute nitric acid (1%) reacts exclusively with Magnesium or Manganese to release hydrogen gas.
Explain the following:
Concentrated nitric acid appears yellow when it is left standing in a glass bottle.
Concentrated nitric acid undergoes decomposition as it is very unstable to heat. On decomposition, they form reddish brown nitrogen dioxide gas which when dissolved in the acid appears yellow in colour.
Explain the following:
an all-glass apparatus is used in the laboratory preparation of nitric acid.
Nitric acid is highly corrosive and can damage plastic, rubber, wood, metal etc. therefore an all-glass apparatus must be used.
