Types of Solutions Concentrated solutions- has a large amount of solute in a solvent Ex maple syrup Dilute solution- has a small amount of solute in a solvent Ex Tap water Think of apple juice: ever seen made from concentrate? This is juice where water has been taken out; dilute solutions are juice that has been watered down

Concentration tells you how much solute is dissolved in a certain amount of solvent (ie 50 g of sugar dissolved in 100 ml of water) See concentration demo 10 g dissolved in 50 ml of water 15 g dissolved in 100 ml of water 6 g dissolved in 25 ml of water

Did you know? White sugar that you buy are really just sugar crystals Sugar beets or sugar cane are boiled down making it more concentrated as the water evaporates leaving behind the sugar crystals

Saturated solutions- involve a solvent that can not dissolve any more solute Ex borax crystal ornaments Unsaturated solutions- a solution where the solvent can dissolve more solute

Activity Saturated solution

If a saturated solution has a concentration of 20 g per 100 ml of water, how many grams of the solute could be dissolved in 50 ml of water? In 400 ml of water?

Solubility is the maximum amount of solute that can be dissolved in a solvent at a certain temperature Three factors affect solubility 1. Temperature 2. Type of solvent 3. Type of solute

Supersaturated- add a solute (ie sugar) to hot water and make a saturated solution. The let the solution cool- what happens? Solution will contain more solute than a saturated solution normally would

For a solute to dissolve in a solvent, it has to be able to bind with the solvent particles If the solute particles do not bind with the solvent particles than the solute is said to be ‘insoluble’
