Why is pure water regarded as a weak electrolyte ?

Text Solution

Verified by Experts

At room temperature
`" " K_w = 1.0 xx 10 ^(-14)`
Therefore , at room temperature
` " " [H_3O^(+) ]= [OH^(-)] =10 ^(-7) " mol " . L^(-1)`
Very low concentration of `H_3O^(+) and OH^(-)` ions in water suggest that it is a weak electrolyte.
