A Level Chemistry 2017 Paper 1 Question 29 Solution - Exclusive
In this exclusive video we want to discuss the suggested solution for A Levels Chemistry (H2 Chemistry) 2017 Paper 1 Question 29.
Let Chemistry Guru, Singapore's top JC Chemistry tuition centre, guide you through this question:
The topic tested in this question is on Electrochemistry, in particular the quantitative determination of species discharged for an electrolytic cell.
We first start with the 2 Faraday's Equations and work out the number of moles of electrons.
We can then determine the moles of copper deposited from the moles of electrons involved in the electrolysis.
From this expression we can see that the moles of copper deposited is only affected by current and time, and not by the concentration of Cu2+ in the solution.
Finally we can compare the options and determine the answer to this question is option C.
