Detailed explanation-1: -Answer: The statement is false. The aqueous solution of an ionic compound conducts electricity because there are plenty of free ‘ions’ in the solution and not free “electrons". In aqueous solution, the ionic compounds conduct electricity because they contain charged particles called cations and anions..
Detailed explanation-2: -Answer and Explanation: This statement is true. Ionic compounds are electrically neutral species as they consist of cations and anions that have totally equal charges that cancel each other. For example-NaCl: Sodium cation has one positive charge and chloride ion has one negative charge that cancels each other.
Detailed explanation-3: -Ionic compounds when dissolved in the water get dissociated into their constituent ions. These ions can conduct electricity and thereby ionic compounds are expected to be good electrolytes. Hence statement 1 is true.
