Koliko mozemo hlorisati vode za pice od hlora, koga dobijamo iz 1000cm3, 36% HCl, gustine 1.2 g/cm3 ?

2HCl---------------------->H2+Cl2

mr=V*ro=1000*1.2=1200 g

ms=w*mr=1200*0.36=432 g

H2O+Cl2---------------->HCl+HClO

n(HCl)=m/Mr=432/36.5=11.836 mol

n(Cl2)=n(HCl)/2=11.836/2=5.918 mol

n(H2O)=n(Cl2)=5.918 mol

V(H2O)=n(H2O)*Vm=5.918*22.4=132.56 l
