Electrochemical Cells starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Electrochemical Cells.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A cell is constructed with a silver electrode in 1 M AgNO3 and a copper electrode in 1 M CuSO4. If E°(Ag+/Ag) = +0.80 V and E°(Cu2+/Cu) = +0.34 V, what is the standard cell potential?
A student connects a voltmeter across the electrodes of a galvanic cell and observes a reading of 1.1 V. What does this value represent?
A student sets up a cell with magnesium and copper electrodes. Which electrode will act as the anode?
Calculate the cell potential for a cell made of Zn and Cu electrodes, given that E°(Zn2+/Zn) = -0.76 V and E°(Cu2+/Cu) = +0.34 V.
Describe the main difference between a galvanic cell and an electrolytic cell.
Describe the main difference between a primary and a secondary cell.
Describe what happens to the mass of the cathode in a galvanic cell during operation.
Explain the function of a salt bridge in a galvanic cell.
Explain why a salt bridge is not always necessary in a single-compartment cell.
Explain why the anode in a galvanic cell is negative.
In a zinc-copper cell, if the zinc electrode is placed in 1 M ZnSO4 and the copper electrode in 1 M CuSO4, which electrode will lose mass during operation?
The standard electrode potential of a cell is measured under standard conditions. Name any two standard conditions.
What is the main purpose of the electrolyte in an electrochemical cell?
