Which of the following solution(s) can conduct electricity?
Which of the following solution(s) can conduct electricity?
Open in App
Solution
The correct options are
B NaCl solution
C Hydrochloric acid
Conduction of electricity is possible only when there are ions/charges in the compound which are free to move.
Pure water contains very few ions, so it is a poor conductor of electricity. Sugar molecules when dissolved in water doesn't dissociate to form ions. Thus, sugar solution is a poor conductor of electricity.
An aqueous solution of an acid conducts electricity because of the presence of hydronium or hydrogen ions(as in HCl).
NaCl solution conducts electricity well because the solution contains ions.
