MCQ

It accepts a proton. It is called as :

✓
A Bronsted acid.
B
A Bronsted base.
C
A strong acid.
D
A weak base.

✓

Answer

Correct option: A.

A Bronsted acid.

A Bronsted acid can accept a proton $\ce{(H^+)}.$ For example a basic salt, such as $\mathrm{Na}^{\oplus} \mathrm{H}^{\ominus}$, can take up a $\mathrm{H}^{+}$from $\mathrm{H}_2 \mathrm{O}$ to form $\mathrm{OH}^{\ominus}$ ions.
$\mathrm{F}^{\ominus}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(\mathrm{l}) \rightleftharpoons \mathrm{HF}(\mathrm{aq})+\mathrm{OH}^{\oplus}(\mathrm{aq})$

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$:

Assertion $A$ : The stability order of +$1$ oxidation state of $\mathrm{Ga}$, In and $\mathrm{Tl}$ is $\mathrm{Ga}<\mathrm{In}<\mathrm{Tl}$.

Reason $R$ : The inert pair effect stabilizes the lower oxidation state down the group.

In the light of the above statements, choose the correct answer from the options given below :
