Question

A salt whose aqueous solution will have a pH of more than 7 will be
(a) K2CO3
(b) K2SO4
(c) NaCl
(d) NH4Cl

Answer 1

Answer:

hey mate here is your answer!!!.

A salt whose aqueous solution will have a pH of more than 7 will be K2CO3.

thus, the option a is correct.

thank u

Answer 2

The salt which has a pH higher than 7 will be basic.

Here, $K_2CO_3$ is basic salt so its pH is more than 7.

Explanation:                                                                                                                          $KOH+ H2CO_3\rightarrow K_2CO_3+ H_2O$

• It determines $K_2CO_3$ can be developed by this action.
• Here $KOH$ is stable base and $H_2CO_3$ is low acid so it will develop basic salt
• Potassium carbonate is a potassium salt that is the dipotassium salt of carbonic acid. It has a purpose as a catalyst. It is a carbonate salt and a potassium salt.
