Question

Prepare one marks questions and answers for the given topic redox reaction four question​

Answer 1

Answer:

Which of the following is not an example of redox reaction?

(i) CuO + H2 ⎯→ Cu + H2O

(ii) Fe2O3 + 3CO ⎯→ 2Fe + 3CO2

(iii) 2K + F2 ⎯→ 2KF

(iv) BaCl2 + H2SO4 ⎯→ BaSO4 + 2HCl

The more positive the value of E⊖ , the greater is the tendency of the species to get reduced. Using the standard electrode potential of redox couples given below find out which of the following is the strongest oxidising agent.

Redox Reactions

(i) Fe3+
