A marine engineer is investigating the corrosion resistance of two different copper-nickel alloys, Alloy C and Alloy D, which are being considered for underwater pipework. The engineer is provided with identical square sheets of each alloy, a balance, two glass beakers, and a container of synthetic seawater.
Devise a quantitative experiment to determine which alloy is more resistant to corrosion.
Practise Edexcel GCSE Chemistry Transition metals, alloys and corrosion with exam-style questions for Foundation and Higher tier. 97 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.
