A solution is a good conductor of electricity and turns blue litmus red. Which ions mainly give acidic properties to this solution?

Answer and explanation

Correct answer: Hydrogen ions

Turning blue litmus red is a characteristic test for an acidic solution. In aqueous school-level chemistry, acids produce hydrogen ions, more precisely hydronium ions formed when H⁺ associates with water. These ions account for acidic properties, and their movement also helps the solution conduct electricity. Therefore option A is correct. Hydroxide ions indicate basicity, while sodium and carbonate ions do not produce the stated acidic behaviour.
