我想問,,,
例如某種acid...
咁佢ge liquid form (pure唔pure有冇關系?) 同 aqueous form 有咩分別?
兩隻係咪都含水份, 可以進行reaction 同埋 form 到 H+ions架??
謝謝解答

All pure acids are molecular compounds, and they do not contain any H+(aq) ion.
A pure acid can be solid, liquid or gaseous at room conditions. For example,
pure citric acid is a solid at room conditions;
pure sulphuric acid is a liquid at room conditions; and
pure hydrogen chloride is a gas at room conditions.

Therefore, "an acid in liquid form" means that it is a pure acid, which is a liquid at room conditions and does not contain any H+(aq) ion.

"An acid in aqueous form" means that that it is the aqueous solution of the acid. The acid is dissolved in water, and is then ionized in water to give H+(aq) ions.
