Titration involves acetic acid as the analyte and sodium hydroxide as the titrant. ph is more than 7 at the equivalency point.

The titration's equivalence point is the moment at which adequate titrant has been introduced to react to all of the material being titrated. A strong acid combined with something like a weak base produces a somewhat acidic salt. Similarly, combining a strong base with a mild acid yields a slightly basic salt.

When acetic acid combines with NaOH, it produces the salt sodium acetate and water. When acetic acid, CH3COOH, interacts with sodium hydroxide, sodium acetate, CH3COONa, and water are formed.

CH3COO- + H2O → CH3COOH + OH-

The acetate ion's reaction raises the ph to over 7.

Moles of acetic acid is equivalent to moles of sodium hydroxide at the equivalence point. As additional sodium hydroxide is added, the solution will become pink.
