equation for the acetic acid reacts with the concentrated sodium hydroxide solution

Dear Student, 

Acetic acid  (CH₃COOH) is acid and Sodium hydroxide (NaOH) is base or alkali. 

Acetic acid neutralises sodium hydroxide base to form salt of sodium acetate and this reaction also generate water. 

CH₃COOH _(aq) + NaOH_(aq) $\to$ CH3COO-Na _(aq) + H2O_(aq) 
                                                     sodium acetate 

This type of reaction is called as acid-base neutralisation reaction.
