# What would be the

Question:

What would be the $\mathrm{pH}$ of a solution obtained by mixing $5 \mathrm{~g}$ of acetic acid and $7.5 \mathrm{~g}$ of sodium acetate

and making the volume equal to $500 \mathrm{~mL}$ ?

$\left(\mathrm{Ka}=1.75 \times 10^{-5}, \mathrm{pKa}=4.76\right)$

1. $4.76<\mathrm{pH}<5.0$

2. $\mathrm{pH}<4.70$

3. $\mathrm{pH}$ of solution will be equal to $\mathrm{pH}$ of acetic acid

4. $\mathrm{pH}=4.70$

Correct Option: 1
