Solution

(a) When the acetic acid reacts with litmus it turns blue litmus red.

(b) When the acetic acid reacts with metals hydrogen is evolved.

$2 C H_{3} - C O O H + Z n ⟶ (C H_{3} - C O O)_{2} Z n + H_{2}$

(c) When the acetic acid reacts with alkalies it forms a salt.

$C H_{3} - C O O H + N a O H ⟶ C H_{3} - C O O N a + H_{2} O$

(d) Acetic acid reacts with alcohols forming esters

$C H_{3} - C O O H + C H_{3} - C H_{2} O H C o n c . H_{2} S O_{4} - ------- \to C H_{3} - C O O - C_{2} H_{5} + H_{2} O$
