A student constructs a simple chemical cell by placing magnesium and copper electrodes into dilute sulfuric acid. After being connected in a closed circuit with a small light bulb for a long period, the bulb goes out and the voltmeter reading falls to 0 V.
State one reason why the voltage of this chemical cell eventually decreases to 0 V.
Practise Edexcel GCSE Chemistry Chemical cells and fuel cells with exam-style questions for Foundation and Higher tier. 17 questions, matched to the Edexcel GCSE Chemistry (1CH0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
