Question

MnO2+4HCL--->Mncl2+2H2O+Cl2
Name the compound (1) oxidised ,(2) reduced.
Define oxidation and reduction?

Hydrogen is oxidised and manganese is reduced.

Oxidation is the process when the element gains oxygen.

Reduction is the process when an element loses oxygen and gains hydrogen.

Answer 2
