Multiple choice If NaOH is added to the solution of CH3COOH H+ ions increases pH decreases C2H3O2- increases HC2H3O2 increase Reveal answer Fill a bubble to check yourself C Correct answer Explanation CH3COOH + NaOH CH3COONa + H2O The salt formed is strong electrolyte. It gives large concentration of CH3COO- (C2H3O2- ions) and Na+ ions.
