Answer : The correct option is, (2) an acid
Explanation:
As we know that when a substance (acid) that dissolves in water, it produces hydronium ion as a positive ion and conjugate base as a negative ion.
For example :
When \(CH_3COOH\) (acid) dissolves in water, it produces hydronium ion as a positive ion and conjugate base as a negative ion.
The balanced reaction will be,
\(CH_3COOH+H_2O\rightarrow H_3O^++CH_3COO^-\)
Therefore, the substance is, (2) an acid
