Q. In Ramsay and Rayleigh's isolation of noble gases from air, the nitrogen of the air is finally converted into

KCETKCET 2011The p-Block Elements - Part2

Solution:

In Ramsay and Rayleigh's isolation of noble gases from air, the nitrogen of the air finally converted into $NaNO _{2}$ and $NaNO _{3} .$

$N _{2}+ O _{2} \stackrel{\begin{array}{c}\text { Electric } \\ \text { discharge }\end{array}}{\longrightarrow } 2 NO$

$2 NO + O _{2} \longrightarrow NO _{2}(g)$

$2 NO _{2}+2 NaOH \longrightarrow NaNO _{2}+ NaNO _{3}+ H _{2} O$
