Action of acetic acid with:
(a) A metal: Acetic acid reacts with a metal producing hydrogen
$\underset{Aceticacid}{2C{H}_{3}COOH}+Mg\to \underset{Magnesiumacetate}{(C{H}_{3}COO{)}_{2}Mg}+H_2\uparrow$

(b) A base/alkali : Acetic acid reacts with a base/alkali producing salt and water.
$\underset{Aceticacid}{C{H}_{3}COO{H}^{+}}+\underset{Sodiumhydroxide}{NaOH}\to \underset{Sodiumacetate}{C{H}_{3}COONa}+\underset{Water}{H_{2}O}$

(c) A carbonate: Acetic acid liberatescarbon dioxide from a carbonate
$\underset{Aceticacid}{2C{H}_{3}COOH}+\underset{Sodiumhydroxide}{N{a}_{2}C{O}_3}\to \underset{Sodiumacetate}{2C{H}_{3}COONa}+H_{2}O+\underset{Carbondioxide}{C{O}_2}\uparrow$

(d) A bicarbonate: Acetic acid liberates carbon dioxide from a bicarbonate
$\underset{Aceticacid}{C{H}_{3}COOH}+\underset{Sod.bicarbonate}{NaHC{O}_3}\to \underset{Sod.acetate}{C{H}_{3}COONa}+H_{2}O+C{O}_2\uparrow$
