When electricity is passed through a common salt solution, sodium hydroxude is produced along with the liberation of two gases X and Y. X burns with a pop sound whereas Y is used for disinfecting drinking water.
(i) Identify X and Y
(ii) Give tha chemical equation for the reaction stated above.
(iii) State the reaction of Y with dry slaked lime.

Text Solution

Verified by Experts

(i) X - Hydrogen
(ii) Y - Chlorine
`2NaCl(aq) + 2H_(2)O(l) rarr 2NaOH(aq) + Cl_(2)(g) + H_(2)(g)`
(iii) Y + slaked lime `(Ca(OH)_(2))`
(iv) `Ca(OH)_(2) + Cl_(2) rarr CaOCl_(2) + H_(2)O`
