Homework Statement
In my book there is a reaction given that is:
MnO2+4HCl→MnCl2+Cl2+2H2O
To prepare Cl2.
And then it is given that in place of HCl, a mixture of H2SO4+NaCl is used... but why?
Homework Equations
None
The Attempt at a Solution
NaCl+H2SO4→NaHSO4+HCl
We here also get HCl. So why should we not use HCl directly? Why should be prefer the latter method?
