This set of Physical Chemistry Multiple Choice Questions & Answers (MCQs) focuses on “Galvanic Cell”.
1. What is the position of the element that always acts as an anode in an electrochemical cell?
a) Lower
b) Higher
c) Middle
d) No effect in position
View Answer
Explanation: Electrolytic cells require a salt bridge both consisting of anode and cathode, and both have a consistent flow of electrons. The position of an element is always higher.
2. The greater value of standard reduction potential greater will be its tendency to get reduced.
a) True
b) False
View Answer
Explanation: Greater standard reduction potential means reduction potential which is the tendency to acquire electrons and thereby be reduced.
3. The greater value of standard reduction potential smaller will be its tendency to form negative ions.
a) False
b) True
View Answer
Explanation: The greater value of standard potential means reduction potential. In reduction potential, there are less negative ions.
4. Secondary cell is _________
a) Non-rechargeable
b) Rechargeable
c) Daniel cell
d) Electrolytic cell
View Answer
Explanation: Secondary cell or rechargeable cell is a type of electrical battery which can be charged, discharged into a load after use.
5. Which one of the following is true for Lead accumulators?
a) Daniel cell
b) Secondary cell
c) Primary cell
d) Galvanic cell
View Answer
Explanation: Lead accumulator is a type of secondary cell or electrical battery which can be charged or discharged after use.
6. What is the density of H2SO4 in lead accumulators?
a) 1.3 g/cm3
b) 1.15 g/cm3
c) 1.25 g/cm3
d) 1.20 g/cm3
View Answer
Explanation: Lead-acid battery is a type of rechargeable battery. It has a very low energy to weight ratio. The density of H2SO4 1.25 g/cm3.
7. What is the capacity of one lead accumulator cell?
a) 2 Volts
b) 3 Volts
c) 4 Volts
d) 5 Volts
View Answer
Explanation: Lead accumulator is a type of rechargeable battery which has the ability to supply high currents. The capacity of lead accumulator cell is 2 Volts.
8. What is anode made up of in an alkaline battery?
a) Zn
b) MnO2
c) AgO2
d) Cadmium
View Answer
Explanation: Alkaline battery is a type of primary battery which depends upon Zinc and Magnesium Oxide. The anode is made up of Zn.
9. What is the strength of the solution whose electrode potential is to be measured?
a) 2 N
b) 2 M
c) 1 M
d) 1 N
View Answer
Explanation: Electrode potential is the electromotive force of a cell built of two electrodes. The strength of the solution is 1 M.
10. What is the percentage of sulfuric acid in lead accumulator?
a) 40%
b) 30%
c) 25%
d) 20%
View Answer
Explanation: The negative plate consists of lead, and the positive plate leads accumulators, with the electrolyte of concentrated sulfuric acid. The sulfuric acid is 30% in lead accumulators.
