1. Koolaid
Sugar/mix + Water Grape Koolaide
solute solvent solution
REACTANTS PRODUCT
Solution - evenly distributed (window cleaner)
Colloid- particles scatter light (milk; fog)
Suspension - visible particles (snow globe; vinegrette)
p693
Na+Cl- +H+2O- H+Cl- + Na+(OH-)
salt + solvent acid + base
Wife Swap - Double Displacement (replacement)

2. Concentration
Dilute - little solute
Concentrated - lot solute
Solubitity - how much solute can be dissolved by a certain
amount of solvent at a certain temperature
saturated can not add anymore
unsaturated can add more
supersaturated over the amount (rock candy)
Affect solubility- temperature
pressure
type of solvent ( Nail water/acid)

3. Acids Bases
H+(hydronium) OH- (Hydroxide ion)
sour bitter
red litmus blue litmus
dissolve metals slippery
Oh! The bitter blue bases are slippery.

6. Digestion
Mouth Mechanical Chewing salivia pH neutral
Stomach Mechanical/ Chemical acid pH 2(hydrocholoric acid)
Intestine Mechanical/Chemical base pH 8(bicarbonate ions)
Digestive enzymes work better at different pH's.
enzymes are catalysts.
