a. When `CI_(2)` gas bubbled through aqueous KOH, a firework explosive (A) is formed along with KCI and `H_(2)O`. Write down the balanced along chemical reaction involved.
b. How many grams of (A) will be formed by 150 L of `CI_(2)` whose pressures is 980 mm Hg at `25^(@)C` ?

Verified by Experts

a. When `CI_(2)` gas is bubbled through aqueous KOH, the following reaction takes place:
`6KOH+3CI_(2)rarr underset("chlorate")underset("Patassium")(KCIO_(3))+5KCI+3H_(2)O`
Firework explosive formed is potassium chlorate, `KCIO_(3)`.
b. `PV=nRT`
Where `P =(980)/(760)atm`
`V =150 L`
`n=?`
`R=0.0821 L atm K^(-1) mol^(-1)`
`T=25^(@)C = 25+273=298 K`
`n=(PV)/(RT)`
`=(980)/(760)xx150xx(1)/(0.0821xx298)`
`= 7. 906` moles
Number of moles of `KCIO_(3)` produced `=(1)/(3)xx` number of moles of `CI_(2)`
`=(1)/(3)xx7.906`
`=2.635`
Mass of `KCIO_(3)` formed `=2.635xx122.5=322.79` g
