Lab 3: Mixtures and Solutions Pre‐lab Questions 1. Name two homogeneous mixtures and two heterogeneous mixtures that you come across daily. Two homogeneous mixtures would be coffee with cream in it or tea with sugar Two heterogeneous mixtures would be cereal and milk and cucumbers and ranch 2. Explain how you would separate a solid mixture of sand and salt using any of the methods mentioned above. A sand and salt mixture could be separated by filtration and this is because salt is soluble in water. If you have a mixture of salt and sand, then by placing the mixture in water you will find that the salt dissolves but the sand remains. You can then filter this new mixture, the salt in the salty water solution passes through the filter paper to form
