Question

The ph of a 0.1m solution of sodium acetate would be

Answer 1

Answer:

It is basic and the ph will be greater than 7

Answer 2

$\huge\underline\mathfrak\purple{Answer}$

In preparing any buffer solution, the solution used for adjusting the pH need not be of the same molarity. So dissolve as you rightly calculated 4.2g of sodium acetate in say 300-400 mL of water. Now adjust its pH using acetic acid (0.1M or 0.2M or more). The exact conc. of this does not matter. Once your desired pH is reached, make up the volume to 500 mL.
