In a redox reaction, both oxidation, as well as reduction, takes place together, oxidation involves loss of electrons while reduction involves the gain of electrons. The redox- reaction may involve a combination of atoms and molecules, displacement of metals, or non-metals.Examples: Zn + CuSO4 → Cu + ZnSO41. In the above equation, which of the following gets reduced?(i) CuSO4(2) Zn(3) ZnSO4(4) None of these2. The oxidising agent generally:(i) Losses the electrons(ii) Gains the electron(iii) Is in a gaseous state(iv) Both b and c3. Identify the oxidising agent in the above reaction(i) Copper(ii) Zinc(iii) Zinc Sulphate(iv) Copper Sulphate4. What is the type of the chemical reaction given in the above example?(i) Double displacement reaction(ii) Displacement reaction(iii) Combination reaction(iv) Decomposition reaction5. Which among the following is(are) double displacement reaction(s)?(i) Pb + Cucl2 → PbCl2 + Cu(ii) Na2SO4 + BaCl2 → BaSO4 + 2NaCl(iii) C + O2 → CO2(iv) CH4 + 2O2 → CO2 + 2H2O
