Detailed Solution

On heating, two molecules of sodium formate forms sodium oxalate and hydrogen gas.

$\underset{Sodium formate}{2 HCOONa} \overset{∆}{\to} \underset{Sodium oxalate}{{Na}_{2} C_{2} O_{4}} + H_{2} ↑$

Oxalic acid formed when sodium oxalate treats with dilute HCl.

${Na}_{2} C_{2} O_{4} + 2 HCl \to H_{2} C_{2} O_{4} + 2 NaCl$

Oxalic acid reaction with KMnO₄and concentrated H₂SO₄ is:

$2 {KMnO}_{4} + 5 H_{2} C_{2} O_{4} + 3 H_{2} {SO}_{4} ⟶ 2 {MnSO}_{4} + 10 {CO}_{2} ↑ + 8 H_{2} O + K_{2} {SO}_{4}$
