Question

Acids do not show acidic behaviour in:

• A. water
• B. absence of water
• C. basic solution
• D. none of these

Answer 1

Answer: (B)

absence of water

Any acid reacts with water forming hydronium ions which are responsible for giving it acidic behaviour and increasing the concentration of hydronium ions which are formed from water giving hydrogen ions and hydroxide ions. Acidity is given by the $pH$ of the solution which increases on the addition of an acid to it.
