1.	In one of the industrial process used for manufacture of sodium hydroxide, a gas X is formed as by - product . The gas X reacts with lime water to give a compound Y which is used as bleaching agent in chemical industry. Identify X and Y giving the chemical equation of the reactions involved.
Answer» Solution :In the manufacture of sodium hydroxide , hydrogen gas and chlorine gas (X) are formed as by - products . When chlorine gas (X) reacts with lime water , if form CALCIUM oxychloride (bleaching powder ) . Y The reactions are `2NaCl(AQ)+2H_(2)O(l) rarr2NaOH(aq)+Cl_(2)(g)+H_(2)(g)` `X-Cl_(2)`(Chlorine gas) `underset("Lime water")(Ca(OH)_(2))(s)+Cl_(2)(g)rarrCaOCl_(2)(s)+H_(2)O(l)` Y - Calcium oxychloride (bleaching powder)
