Question

What are the key differences between solutions and mechanical mixtures? Give two examples of each. -Science

Answer 1

Answer:

A mixture is two or more substances combined. There are no chemical reactions involved, so no new substances are made. Mixtures can often be separated by physical means. For example, a mixture of sand and water could be separated by filtration. A mixture of sand and iron filings could be separated magnetically.

A solution is one kind of mixture. It’s commonly the combination of a liquid and a solid, so that the particles of the solid mix with those of the liquid so that they can’t be separated by filtration. However solutions may be separated in other ways. For example, in salt water the salt and the water can be separated by distillation.
