Sample questions
-
1.Methyl orange is:
- A.Pink in acidic medium, colourless in basic medium
- B.Yellow in acidic medium, pink in basic medium
- C.Colourless in acidic medium, pink in basic medium
- D.Pink in acidic medium, yellow in basic medium
-
2.Lime juice has a sour taste while lime water is slightly bitter. Why ?
- A.Lime water is alkaline
- B.Lime juice contains citric acid
- C.Both (a) and (b) are correct
- D.None of the above
-
3.Why is it necessary to determine the exact ratio of sodium hydroxide and sulphuric acid in the preparation of sodium sulphate?
- A.To ensure complete neutralisation without excess reactants, as both are soluble and cannot be removed by filtration.
- B.To speed up the reaction and reduce the time required for preparation.
- C.To form a precipitate that can be easily filtered out from the solution.
- D.To increase the yield of sodium sulphate by adding excess sodium hydroxide.
-
4.Solution 'A' has pH-1 whereas solution 'B' has pH-4. In this context choose the correct statement
- A.'A' is a weak acid in comparison to B
- B.'A' and 'B' both are weak bases
- C.'A' is a strong acid in comparison to B
- D.'A' is strong base in comparison to 'B'
-
5.How is an acid prepared from a salt? Select the correct method and provide the corresponding equation as an example.
- A.By reacting the salt with a stronger acid; e.g., NaCl + H₂SO₄ → NaHSO₄ + HCl
- B.By dissolving the salt in water; e.g., NaCl + H₂O → HCl + NaOH
- C.By heating the salt with a base; e.g., NaCl + NaOH → Na₂O + HCl
- D.By reacting the salt with a metal; e.g., NaCl + Zn → ZnCl₂ + Na
