Question

Which statements about conductivity of distilled water are correct?

• A. It possesses almost non-conducting nature
• B. It is obtained by distillation of water several times
• C. It is contaminated with little acid
• D. None of the above

Answer 1

Answer: (A), (B)

It possesses almost non-conducting nature
It is obtained by distillation of water several times

Water is a weak electrolyte and is almost non conducting in nature as hardly any ions are present in pure water. However if impurities are present, then the conductivity will be high. In order to obtain the true value of the conductivity of water, these ions are removed by distilling the water several times.
