1.	What is redox reactions ? Identity the substance oxidised and the substance reduced in the following reactions : MnO_(2)+4HCl to MnCl_(2)+2H_(2)+Cl_(2)
Answer» Solution : As it is clear, MANGANESE decrease its OXIDATION number from +4 to +2. HENCE, `MnO_2` gets reduced and it is an OXIDISING agent. Chlorine atom in HCl increases its oxidation number from -1 to 0. Thus, HCl gets oxidised and it is reducing agent.
