Aqueous solution of an acid contains

Options

A. `H^(+)`
B. `H_(3)O^(+)`
C. `H_(2)O^(+)`
D. Both `H^(+) and H_(3)O^(+)`

Answer

B

Explanation

In aqueous solution, the `H^(+)` ions given by acid combine with water to given `H_(3)O^(+)` (hydronium ion). So, aqueous solution of an acid contains only `H_(3)O^(+)`.
