A solution conducts electricity but does not contain solid sodium chloride. What is the best reason for conductivity of an acidic solution?

Answer and explanation

Correct answer: Ions formed in water

Electrical conduction through a solution requires mobile charged particles. An acid ionises or reacts with water to produce hydronium ions and corresponding negative ions; these ions move toward opposite electrodes and carry electric current. Solid sodium chloride is not necessary, because dissolved ions from the acid are sufficient for conduction. Therefore option A is correct. Colour, the glass container and low temperature do not provide the mobile charge carriers required for an electric current.
