Questions + Answers key
Take MCQ Chemistry Test1.
How would you know whether a redox reaction is taking place in an acidic, alkaline or neutral medium?
2.
What is the most essential conditions that must be satisfied in a redox reaction?
3.
Why is anode called oxidation electrode, whereas the cathode is called reduction electrode?
4.
Zn rod is immersed in CuSO4 solution. What will your observe after an hour? Explain your observation in terms of the redox reaction.
5.
Nitric acid is an oxidising agent and reacts with PbO but it does not react with PbO2 Explain why?
1.
1. If H+ any acid appears on either side of the chemical equation, the reaction occurs in acidic solution.
2. If OH- or any base appears on either side of the chemical equation, the reaction occurs in basic solution.
3. If neither H+, OH- nor any acid or base is present in the chemical equation, the solution is neutral.
2.
In a redox reaction, the total number of electrons lost by the reducing agent must be equal to the number of electrons gained by the oxidising agent.
3.
At the anode, loss of electron takes place (ie.,) oxidation occurs. Hence called as oxidation electrode.
At the cathode, the gain of electrons takes place (ie.,) reduction occurs. Hence called as reduction electrode.
4.
1. The blue colour of CuSO4 solution will get discharged and reddish brown copper metal will be deposited on Zn rod.
2. This is because blue colour Cu2+ (in CuSO4) gets reduced to Cu by accepting two electrons from Zn, which gets oxidised to colourless ZnSO4.
5.
(i) Nitric acid in an oxidising agent. It oxidises an element from lower oxidation state to the higher oxidation state In PbO, lead is in lower oxidation state of +2. HNO3 oxidises lead from Pb2+ to Pb4+
PbO + 2HNO3 \(\longrightarrow\) Pb (NO3)2 + H2O
(ii) In PbO2, lead is in +4 oxidation state and cannot be oxidised further. Therefore no reaction takes place.
