Final answer:
To find the pH of a solution of acetic acid, use the given pKa value and concentration of the acid. Apply the equation pH = pKa + log([A-]/[HA]). For a solution with 0.35 M acetic acid and a pKa of 4.76, the pH is approximately 4.34.
Step-by-step explanation:
In order to determine the pH of a solution of acetic acid, you need to use the given pKa value and the concentration of the acid. The pH can be calculated using the equation pH = pKa + log([A-]/[HA]), where [A-] is the concentration of the conjugate base and [HA] is the concentration of the acid.
In this case, the concentration of acetic acid is given as 0.35 M. Since acetic acid is a weak acid, it will partially dissociate in water. Using the given pKa value of 4.76, we can find the concentration of the conjugate base. According to the equation, [A-]/[HA] = 10^(pH - pKa).
By substituting the values, we have 0.6/0.35 = 10^(pH - 4.76). Taking the logarithm of both sides, we get pH - 4.76 = log(0.6/0.35). Solving this equation, we find that the pH of the solution is approximately 4.34.
