Question

Calculate the pH of a solution prepared by dissolving 0.150 mol of acetic acid and 0.300 mol of sodium acetate in water sufficient to yield 1.00 L of solution

Answer 1

The pH of a solution prepared is 5.056

Step-by-step explanation:

The computation of the pH of a solution is shown below:

For a buffer solution,

As we know that

pH = pKa+ log ( whether it is a salt or anacid)

pKa = -log ( 1.76 × 10^5)

pH = -log ( 1.76 ) + 5 + log ( 2)

pH = 5 + 0.301 - 0.245

= 5.056

Hence, the pH of a solution prepared is 5.056 and the same is to be considered
