Question

when electricity is passed through a common salt solution sodium hydroxide is produced along with the liberation of two gases X and Y . the gas X burns with a pop sound the Y is used for disinfecting drinking water Q ) a ) identify X and Y b) give the chemical reaction for the equation

Answer 1

X = Hydrogen ( H 2)

Y = Chlorine ( Cl 2 )

Reaction :

2 NaCl ( aq ) + 2 H2O ( l ) ----> 2 Na OH ( aq) + Cl2 ( g) + H2 ( g)

Answer 2

X is hydrogen and Y is chlorine.

2H2O +NACL-H2+CL +Na(oh)2
