The aqueous solution of sodium acetate with minimum pH is

A

`0.01` M

B

`0.001 M `

C

`0.0001 M `

D

`0.1 M `

Text Solution

Verified by Experts

The correct Answer is:
C
Sodium acetate is a salt of weak acid and strong base. So if the concentration of it is less than it will be less basic and the `[OH^(-)]` in aqueous solution will also is less.
`CH_(3)COONa + H_(2)O hArr underset ("Weak acid")(CH_(3)COOH) + underset ("Strong base ")(NaOH)`
`NaOH hArr Na^(+) +OH^(-)`
So for minimum concentration pH value will be minimum (though it will be above 7).
