Question

Which of the following statement is incorrect?

  1. Calcium carbonate is always preferred during the laboratory preparation of carbon dioxide.
  2. The solubility of carbon dioxide increases with an increase in pressure.
  3. Carbon dioxide reacts with magnesium and aluminum to form their corresponding carbonates.
  4. Carbon dioxide is used to manufacture aerated drinks to give them a tangy taste.

hintHint:

Metal oxides reacted with carbon dioxide forms metal carbonates.

The correct answer is: Carbon dioxide reacts with magnesium and aluminum to form their corresponding carbonates.

    Read the following paragraph carefully. To a small quantity of (X), a few drops of HCl are added. Consequently, a colorless, odorless gas (Y) is formed. This gas(Y) on passing through lime water turns it milky due to the presence of (Z), and then the milkiness disappears due to the formation of (W)
