Question

A buffer solution is prepared by adding 13.74 g of sodium acetate (NaC2H3O2) and 15.36 g of acetic acid to enough water to make 500 mL (three significant figures) of solution. Calculate the pH of this buffer.

Answer 1

A buffer solution is prepared by adding 13.74 g of sodium acetate (NaC2H3O2) and 15.36 g of acetic acid to enough water to make 500 mL of solution.

Calculate the pH of this buffer.

Step-by-step explanation:

The pH of a buffer solution can be calculated by using the Henderson-Hesselbalch equation:

`pH=pKa+log([salt])/([acid])`

The pH of the given buffer solution can be calculated as shown below:
