An industrial chemist is handed two unlabelled beakers containing clear, colourless aqueous solutions. One beaker contains calcium ions (textCa2+\\text{Ca}^{2+}textCa2+) and the other contains aluminium ions (textAl3+\\text{Al}^{3+}textAl3+).
Devise a plan to identify which beaker contains which metal ion using chemical reagents. Describe the steps you would take and the expected observations.
Practise Edexcel GCSE Chemistry Qualitative analysis: tests for ions with exam-style questions for Foundation and Higher tier. 127 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.
