उत्तर

Concentrated nitric acid is a stronger oxidizing agent due to nascent oxygen which it gives on decomposition.
\[\ce{\underset{\text{Conc.}}{2HNO3} -> H2O + 2NO2 + \underset{\text{nascent oxygen}}{[O]}}\]

\[\ce{\underset{\text{Dilute}}{2HNO3} -> H2O + 2NO + \underset{\text{nascent oxygen}}{3[O]}}\]

Describe what you see when concentrated nitric acid is added to copper.


X, Y and Z are three crystalline solids that are soluble in water and have a common anion.

To help you to identify X, Y and Z, you are provided with the following experimental observations. Copy and complete the corresponding inferences in (a) to (e).

  1. A reddish-brown gas is obtained when X, Y and Z are separately warmed with concentrated sulphuric acid and copper turning added to the mixture.
    INFERENCE 1: The common anion is the ______ ion.
  2. When X is heated, it melts and gives off only one gas which re-lights a glowing splint.
    INFERENCE 2: The cation in X is either ______ or ______.
  3. The action of heat on Y produces a reddish-brown gas and yellow residue which fuses with a glass of the test tube.
    INFERENCE 3: The metal ion present in Y is the ______ ion.
  4. When Z is heated, it leaves no residue. Warming Z with sodium hydroxide solution liberates a gas which turns moist red litmus paper blue.
    INFERENCE 4: Z contains the ______ cation.
  5. Write the equations for the following reactions:
    1. X and concentrated sulphuric acid (below 200°C). (One equation only for either of the cations given in INFERENCE 2)
    2. The action of heat on Y.
    3. Concentrated nitric acid is added to copper turnings kept in a beaker.
