Calculate the [H+] and pH of a 0.0010 M acetic acid solution. The Ka of acetic acid is 1.76×10−5. Use the method of successive approximations in your calculations.

Explanation:

Hello,

In this case, dissociation reaction for acetic acid is:

For which the equilibrium expression is:

Which in terms of the reaction extent could be written as:

Thus, solving by using a solver or quadratic equation we obtain:

And clearly the result is 0.000123M, which also equals the concentration of hydronium ion in solution:

Now, the pH is computed as follows:

Best regards.
