Electrochemical Cells & Electrolysis — Drills · Grade 11 Science
Chapter: Redox, Cells & Nuclear ChemistryWhat these drills covers
By the end of Electrochemical Cells & Electrolysis you should be able to:
- I can trace electron and ion paths and identify anode/cathode processes.
- I can calculate a standard cell voltage and link electrical charge to reaction amount.
2 questions, numeric and written answer, each with a worked explanation.
Vocabulary used: galvanic cell, electrolysis, Faraday constant.
Problem 1
A 2 A current runs 30 s. Find transferred charge.
Hints
Write the relationship first; substitute with consistent units.
Answer and explanation
60 C
Q=It=60.
Problem 2
What does a salt bridge carry?
Answer and explanation
Ions move through it to maintain charge balance; external electrons use the wire.
Response criteria
- State a scientifically accurate conclusion.
- Show the calculation or mechanism that supports it.
- Include units, conditions, or limits where relevant.
