Dear
Student,

Sodium react with water to produce sodium hydroxide and
hydrogen 
Sodium hydroxide 
react with carbon dioxide to produce sodium carbonate and water
Sulfur oxide react with sodium carbonate to produce sodium sulfite
and carbon dioxide Sodium sulfide react with sodium sulfite and
iodine to produce sodium thiosulfate and sodium iodide

Na →H2O   H2 + NaOH→CO2Na2CO3 →SO2Na2SO3 →Na2S+I2Na2S2O3 + NaI                                     A                   B                      C                                 D

plz explain with chemical reactions 43 . Na → H 2 O A → CO 2 B → SO 2 C → Na 2 S + I 2 D The compound D is : - 1 Na 2 SO 4 2 Na 2 S 4 O 6 3 Na 2 S 2 O 5 4 Na 2 S 2 O 3

plz explain with chemical reactions

$43 . Na \overset{H_{2} O}{\to} A \overset{{CO}_{2}}{\to} B \overset{{SO}_{2}}{\to} C \overset{{Na}_{2} S + I_{2}}{\to} D The compound D is : - (1) {Na}_{2} {SO}_{4} (2) {Na}_{2} S_{4} O_{6} (3) {Na}_{2} S_{2} O_{5} (4) {Na}_{2} S_{2} O_{3}$
