pH of sodium carbonate `(Na_(2)CO_(3))` solution will be

A

7

B

`gt7`

C

`lt7`

D

1

Text Solution

Verified by Experts

The correct Answer is:
B
`Na_(2)CO_(3)+2H_(2)Otounderset("Strong base")(2NaOH)+underset("Weak acid")(H_(2)CO_(3))` Since it it sa salt of weak acid and strong base , it is basic in nature with `pHgt7` .
