उत्तर

When nitric acid is added to washing soda carbon dioxide will form which when passed through a freshly prepared lime water, turns lime water milky.
\[\ce{Na2CO3 + 2HNO3 -> 2NaNO3 + H2O(I) + CO2}\]

\[\ce{Ca(OH)2 + CO2 -> CaCO3 + H2O}\]

    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.
