प्रश्न
The reaction between the red lead and hydrochloric acid is given below:
\[\ce{Pb3O4 + 8HCl -> 3PbCl2 + 4H2O + Cl2}\]
Calculate the volume of the chlorine evolved at S.T.P.
उत्तर
1 V Pb3O4 produces 1 V Cl2
685g of Pb3O4has volume = 22.4 litres = volume of Cl2 produced
So, 6.85 Pb3O4 will produce = `(6.85 xx 22.4)/685` = 0.224 litres
