Question

All of the following are examples of electrolytic solutions, except __.

A) Ocean water
B) Pure water
C) Strong hydrochloric acid
D) potassium chloride solution

Answer 1

the answer is B) pure water because pure water is a poor conductor of electricity.. thus a poor electrolyte

Answer 2

Answer: 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
`H^+` ions and thus act as good electrolyte.

`HCl\rightarrow H^++Cl^-`

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

`KCl\rightarrow K^++Cl^-`
