Question

Select a pair of basic salt among the following
(a) Sodium chloride and sodium acetate
(b) Sodium acetate and sodium bicarbonate
(c) Sodium carbonate and sodium sulphate
(d) Sodium nitrate and sodium oxalate​

Answer 1

The pair of basic salt among the following is Sodium chloride and sodium acetate.

Explanation:

1. Basic salts are those salts that are formed by the action of a weak acid and a strong base.
2. Sodium acetate and Sodium bicarbonates are the basic salts among all the given salts.
3. The chemical reaction occurs as follows:
4. $CH_{3}COOH + NaOH$ → $CH_{3} COONa+H_{2}O$
5. In this reaction acetic acid is a weak acid and sodium hydroxide is a weak base, therefore it produces basic salt such as sodium acetate.
6. $H_{2}CO_{3} +NaOH$ → $NaHCO_{3} +H_{2}O$
7. Hydrogen carbonate is is a weak acid and sodium hydroxide is a strong base therefore it forms basic salt such as Sodium bicarbonate

Answer 2

Explanation:

Sodium acetate and sodium bicarbonate

Description: When an incomplete neutralization occurs between a strong base and weak acid we get a Basic salt. Here same happens in case of Sodium acetate and sodium bicarbonate whose strong base and acid are as follows

Sodium Acetate : strong base- Sodium hydroxide; weak acid- acetic acid

the chemical reaction occurs as follows:

$CH_3COOH+NaOH- > CH_3COONa+H_2O$                        

Sodium Bicarbonate: strong base- Sodium Hydroxide; weak acid- carbonic acid.

The chemical reaction occurs as follows:

$H_2CO_3+NaOH- > NaHCO_3+H_2O$

Hence option b is correct.
