How We Measure pH
Acids and Alkalis
pH Scale
Acid pH
Alkali pH
Neutral pH
pH 1-6 = Acid
pH 7 = Neutral
Examples: Pure Water, Milk, Saliva, Blood
pH 8-14 = Alkali
Examples: Lemon Juice, Hydrochloric Acid, Gastric Acid, Vinegar
Examples: Bleach, Sodium Hydroxide, Ammonia, Borax, Baking Soda
Making Salt
Uses of Salt
Adding Flavour to Food
Bath Utilisation
Melting Ice
Preservation
Agriculture
Used to Dehydrate
Making Salt Equations
Metal+Acid→Salt+Hydrogen
Metal Oxide+Acid→Metal Salt+Water
Metal Carbonate→Metal Salt+Water+Carbon Dioxide
Examples:
Magnesium+Nitric Acid→Magnesium Nitrate+Hydrogen
Calcium+Hydrochloric Acid→Calcium Chloride+Hydrogen
Examples:
Iron Oxide+Nitric Acid→Iron Nitrate+Water
Sodium Oxide+Hydrochloric Acid→Sodium Chloride+Water
Gold Carbonate+Sulfuric Acid→Gold Sulfuric+Water+Carbon Dioxide
Potassium Carbonate+Nitric Acid→Potassium Nitrate+Water+Carbon Dioxide
