You will learn about mixtures and solutions. Discover how to identify substances by their solubility, and explore techniques to separate mixtures.
After completing this tutorial, you will be able to complete the following:
What is solubility?
~ Solubility is the ability of a substance to dissolve in a liquid.
How do sugar and chalk dust differ from one another in terms of solubility?
~ While sugar has a very high solubility, chalk dust has a low solubility. This means that sugar will dissolve in water, but chalk dust will not.
How can you distinguish a substance with high solubility from one with low solubility?
~ When a substance is highly soluble, a large amount of it will dissolve in water. When a substance is not very soluble, a small amount of it will dissolve in water.
If you know that 35 grams of substance A and 40 grams of substance B will dissolve in 125 milliliters of water, how can you distinguish between these two substances?
~ To distinguish between these two substances, you will need two containers filled with 125 milliliters of water. Place 40 grams of each substance in the water. The substance that completely dissolves will be substance B and the one that dissolves only partially will be substance A.
