Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid. true or false
JulsSmile [24]

Answer:

The given statement is true.

Explanation:

Chlorine gas is prepared by heating manganese dioxide with hydrochloric acid.T he reaction takes place in two steps

1) Reaction between manganese dioxide and HCl gives manganese(II) chloride along with water and nascent oxygen.

MnO_2+2HCl\rightarrow MnCl_2+H_2O+O...[1]

2) Then this nascent oxygen formed in above reaction oxidizes HCl into water and chlorine gas.

2HCl+O\rightarrow Cl_2+H_2O..[2]

So , the net chemical reaction comes out to be:

MnO_2+4HCl\rightarrow MnCl_2+H_2O+Cl_2
