Question

25. Why do acid not show acidic behaviour in the absence of water? Why does distilled water not conduct
electricitu where as rain water does?
​

Answer 1

Explanation:

Distilled water is pure form of water which do not contain any solute in it. Therefore it cannot conduct electricity because it does not contain ions while rain water contains dissolved salts and acids which dissociates in ions and conducts electricity.

Answer 2

Answer:

The acidic behavior of an acid is due to the presence of hydrogen ions [H+ (aq) ions] which are produced only when acids are dissolved in water. In the absence of water, acids do not produce hydrogen ions and hence do not show acidic behavior
