Abuffer is prepared by adding 20.0 g of sodium acetate to 480 ml of a 0.160 m acetic acid solution. determine the ph of the buffer. the ka of acetic acid is 1.8 x 10-5

Hello!

The chemical reaction for the dissociation of Acetic Acid is the following:

CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺

To solve the problem we are going to use the Henderson-Hasselbach Equation, as follows, but first we need to know the pKa:







So, the pH of this solution is 5,24

Have a nice day!

The correct answer would be b) volume versus temperature, because they are also directly proportional.
