Question

Pure water is :

1) non-electrolyte 2) weak electrolyte

3) almost non-ionized 4) Ions are not free to move

• A. All
• B. only 2
• C. 1 and 3
• D. 1, 2, 3

Answer 1

The correct option is C 1 and 3

For pure water $(K_w={10}^{-14})$, conc. of $H^{+}$ and $O{H}^{-}$ ions are $\approx {10}^{-7}$ which is very low.

$\therefore$ It is almost non-ionised and non-electrolyte
