Mixtures and Solutions

Mixtures two or more materials stirred together How do you separate mixture? Hand separation Screening Filtering

Solutions a special mixture formed when a material dissolves in water How do you separate solution? Evaporation

Solubility or most soluble The property of a substance that tells how it dissolves in a liquid. Which is the most soluble? Salt Baking soda Citric Acid

Saturated Solution is when a solute dissolves in a solvent until no more will dissolve. How can you dissolve more in a saturated solution? Heat Add more solvent

Saturated solutions All saturated solutions made at the same temperature always have the same ……… Concentration.

Crystal Regular form Examples: Salt - Citric Acid - Epsom Salt - Snowflake -

Concentration the amount of material dissolved in an amount of liquid. Mathematically Which is more concentrated? 1 in 25, 2 in 50, 3 in 100, 4 in 125

Dilute to make a solution less concentrated To dilute something: Add more solvent - water or the liquid

Chemical Reactions When two or more materials (chemicals)are mixed together and a change occurs. Evidence of a chemical change: •Fizzing, bubbling, or releasing gas •Temperature change. •Forms a new substance. (precipitate)
