Question

Which of these is a bases? A. Vinegar B. HCI C. NaOH D. HNO3

Answer 1

The corresponding compound that is classified as a base, would be C. NaOH. The rest are all acids as they contain a hydrogen atom that can dissociate into an aqueous solution, water specifically.

Answer 2

Answer: The correct option is (C).

Step-by-step explanation:

Bases are the compounds which give hydroxide ions in their aqueous solution.

`BOH\rightarrowB^++OH^-`

NaOH is a base and gives hydroxide ions(
`OH^-`) in its aqueous solution.

`NaOH\rightarrow Na^++OH^-`

Whereas other enlisted option are acids and acids in their aqueous solution give hydronium ions that is
`H^+`.

So, the correct option is (C).
