Question

Determine whether an aqueous solution of each of the following salts will be acidic, basic, or neutral. Ba3(PO4)2 NaCN

Answer 1

Answer: Both the salts are basic salts.

Step-by-step explanation:

Salts are formed when an acid reacts with a base during a neutralization reaction.

When a strong acid and a weak base reacts, it leads to the formation of acidic salt.

When a strong base and weak acid reacts, it leads to the formation of basic salt.

When a strong acid and strong base or weak acid and weak base reacts, it leads to the formation of neutral salts.

`Ba_3(PO_4)_2` is a salt which is formed by the combination of
`H_3PO_4\text{ and }Ba(OH)_2`. Phosphoric acid is a weak acid and barium hydroxide is a strong base. So, the given salt is a basic salt.

`NaCN` is a salt which is formed by the combination of
`HCN\text{ and }NaOH`. Hydrogen cyanide is a weak acid and sodium hydroxide is a strong base. So, the given salt is a basic salt.

Hence, both the salts are basic salts.
