The aqueous solution of sodium acetate with minimum pH is

Options

A. `0.01` M
B. `0.001 M `
C. `0.0001 M `
D. `0.1 M `

Answer

C

Explanation

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).
