Question

Which of these will react with oxygen to form an acidic oxide?
(1) Sodium
(2) Sulphur
(3) Calcium
(4) Zinc

Answer 1

sulphur will react with oxygen to form an acidic oxide.

Answer 2

Sulphur reacts with oxygen to form an acidic oxide

• Metals react with oxygen to form basic oxides
• Non-metals react with oxygen to form acidic oxide
• Basic oxides when dissolved in water forms bases and acidic oxides when dissolved with water form acids
• Sulphur is a chalcogen (non-metal) from Group 6A in the periodic table. Since it is a non-metal, it forms acidic oxides when it reacts with oxygen
• Sodium (Group 1 in the periodic table), Calcium (Group 2 in the periodic table), and Zinc (Group 12 in the period table) are all metals, and hence they form basic oxides when reacting with oxygen

Hence, the correct answer is (2) Sulphur
