Question

Which of the following titrations will have the equivalence point at a pH more than 8?​

Answer 1

★Aɴsᴡᴇʀ★

Acetic acid is a weak acid and sodium hydroxide is strong base. Salts of the two will hydrolyse to give basic solution. So, at neutral point, pH of the solution will be greater than 8.

Answer 2

Answer:

Explanation:

Acetic acid is a weak acid and sodium hydroxide is strong base. Salts of the two will hydrolyse to give basic solution. So, at neutral point, pH of the solution will be greater than 8.

If that number is greater than the number of moles of base B, the titration is past the equivalence point. To find the pH, first simply find the moles of excess H3O+. The excess can be calculated by subtracting initial moles of analyte B from moles of acidic titrant added, assuming a one-to-one stoichiometric ratio.
