Each Part: 1 Mark

Action of acetic acid with:

(a) Litmus: It turns blue litmus red.

(b) Metals: Acetic acid reacts with metals like zinc, magnesium etc., producing hydrogen.

(c) Alkalies: Acetic acid forms salts with alkalies
$\underset{Aceticacid}{C{H}_{3}COOH}+NaOH\to \underset{Sodiumacetate}{C{H}_{3}COONa}+H_{2}O$

(d) Alcohol: Acetic acid reacts with alcohol in the presence of conc. $H_{2}S{O}_4$, forming esters.
$\underset{Aceticacid}{C{H}_{3}COOH}+\underset{Ethylalcohol}{C_2{H}_{5}OH}\stackrel{Conc.H_{2}S{O}_4}{\to }\underset{Ethylacetate\left(Ester\right)}{C{H}_{3}COO{C}_2{H}_5}+H_{2}O$
