Explanation:
Detailed explanation-1: -There is no excess NaOH. The solution is NaCl at the equivalence point. When a strong acid completely neutralizes a strong base, the pH of the salt solution will always be 7.
Detailed explanation-2: -If you have a complete neutralization, meaning that equal amounts of hydronium and hydrogen ions react, the pH of the resulting solution will be equal to 7, which is the pH of water at 20∘C .
Detailed explanation-3: -A solution of sodium hydroxide (NaOH) has a pH of 10.
Detailed explanation-4: -The pH of a solution of hydrochloric acid is 4.
