Q 1260478315.     A gaseous mixture of `Cl_2 ClO_p(p) (p` an integer` ) `and `NH_3` in the molar ratio `1 : 4 : 6` having a total volume `110` ml is taken and underwent sparking `I` causing only decomposition of oxide of `Cl_2` gas and `O_2` gas resulting a rise in Volume by `20` ml . On sparking `II` only partial decomposition of `NH_3` took place and the resulting mixture on passing through water showed a contraction by `20` ml .On sparking `III` of the resulting mixture some drops of water formed with only one more product and the mixture when passed through `KOH (`absorbs `Cl_2` only `)` showed no volume change . Form this information calculate
Volume change that would be observed when the mixture after `III` sparking is over is passed (through alkaline pyragallol ).
