Question

26 A substance that dissolves in water and produces hydronium ions as the only positive ions in the solution is classified as

(1) an alcohol (3) a base
(2) an acid (4) a salt

Answer 1

(2) an acid
It's caused by an Arrhenius acid mixing with water to form Hydronium and Hydroxide ions

Answer 2

Answer : The correct option is, (2) an acid

Step-by-step 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
