Question

A compound that dissolves in water which barely conducts electrical current can probably be:

• A. a strong electrolyte
• B. an ionic salt
• C. a strong acid
• D. a strong base
• E. none of the above

Answer 1

The correct option is E none of the above

A compound that dissolves in water which barely conducts electrical current can probably be a non electrolyte such as urea or glucose. It does not dissociates in aqueous solution. Hence, it does not provides current carrying ions. On the other hand, a strong electrolyte such as an ionic salt ($NaCl$ or $KCl$), or a strong acid (sulphuric acid) or a strong base ($NaOH$ or $KOH$) completely dissociates in aqueous solution and provides current carrying ions and conducts electrical current .
