AQA GCSE Chemistry What is a mixture? - ANS Two or more elements not chemically bonded What is the difference between a compound and a mixture? - ANS Compounds have a fixed composition whereas mixtures do not. Mixtures are not chemically bonded but compounds are. Describe the process of filtration - ANS Pour the mixture onto the filter paper, the liquid simply passes through the filter paper into the flask. The insoluble solid cannot pass through and so it stays on the paper...
