All of the following are examples of electrolytic solutions, except

a) ocean water
b) pure water
c) strong hydrochloric acid
d) potassium chloride solution

B) Pure water

Explanation: Electrolytes are those solutions which consists of ions and thus can easily conduct electricity through them.

a) Ocean water contains dissolved minerals which act as electrolytes and hence act as a good electrolyte.

b) Pure water is present in undissociated form due to strong hydrogen bonding and thus due to the absence of ions, act as a non electrolyte.

c) Strong hydrochloric acid: is a strong acid which easily dissociates to give ions and thus act as good electrolyte.

d) Potassium chloride is a salt which act as good electrolyte due to easy dissociation of ions in water.
