Making copper sulfate insoluble base worksheet, Edexcel iGCSE 9-1 chemistry

Worksheet on making copper sulfate crystals from copper oxide (insoluble base method) covering two pages for Edexcel 9-1 iGCSE chemistry, versions in colour and in black and white for printing with a mark scheme. Covers removing the excess copper oxide and letting crystals form. There’s a link to a recommended video from Pearson.

The content is divided over the two pages: the first page is more “directly on the topic” questions and could be used on its own for students at the time they cover copper sulphate or do the practical, the second page is more extension and for “final exam revision”: based on student questions and points that came up from discussing the video, I made the second page cover more synoptic questions making connections with other topics, like temperature and rate of reaction. The worksheet is targeted towards building exam technique and written question skills, so doesn’t include a full practical method. Questions consulted include 2C June 2016 Q7 for technique (I recommend this for exam-style practice) and 1CR June 2019, question 5d for rate of reaction and temperature.

I have a similar worksheet for AQA GCSE chemistry.
