Solution

(i) When a pinch of sodium hydrogencarbonate NaHCO₃ is added to ethanoic acid (CH₃COOH), brisk effervescene is formed due to evolution of CO₂ gas.

$N a H C O_{3}$ + $C H_{3} C O O H$ $\to$ $C H_{3} C O O N a$ + $H_{2} O$ + $C O_{2}$

(ii) When ethanol (C₂H₅OH) is oxidised with acidified potassium dichromate(K₂Cr₂O₇), ethanoic acid is formed.

$C H_{3} C H_{2} O H$ $a c i d i f i e d K_{2} C r_{2} O_{7} - ---------- \to$ $C H_{3} C O O H$
