Question

Aqueous solution of Na2S2O3 on reaction with Cl2 gives (A) Na2S4O6 (B) NaHSO4 (C) NaCl (D) NaOH

Tardigrade Admin · Accepted Answer

Sodium thiosulphate, Na2S2O3 gets oxidised by chlorine water as Na2S2O3 + 4Cl2 + 5 H2O longrightarrow 2NaHSO4 + 8HCl FeCl3 oxidises Na2S2O3 to Na2S4O6

Q. Aqueous solution of $N a_{2} S_{2} O_{3}$ on reaction with $C l_{2}$ gives

$N a_{2} S_{4} O_{6}$

$N a H S O_{4}$

$N a Cl$

$N a O H$

Sodium thiosulphate, $N a_{2} S_{2} O_{3}$ gets oxidised by chlorine
water as
$N a_{2} S 2 O_{3} + 4 C l_{2} + 5 H_{2} O ⟶ 2 N a H S O_{4} + 8 H Cl$
$F e C l_{3}$ oxidises $N a_{2} S_{2} O_{3}$ to $N a_{2} S_{4} O_{6}$
