Acids and Alkalis | Mind Map

pH Scale

Acid pH

pH 1-6 = Acid

Examples: Lemon Juice, Hydrochloric Acid, Gastric Acid, Vinegar

pH 1 = Strong Acidity

Neutral pH

pH 7 = Neutral

Examples: Pure Water, Milk, Saliva, Blood

Alkali pH

pH 8-14 = Alkali

Examples: Bleach, Sodium Hydroxide, Ammonia, Borax, Baking Soda

pH 14 = Strong Alkalinity

Indicators for Acids and Alkalis

How We Measure pH

Universal Indicator Paper

pH Meter

Phenolphthalein

Making Salt

Uses of Salt

Adding Flavour to Food

Bath Utilisation

Melting Ice

Used to Dehydrate

Making Salt Equations

Metal+Acid→Salt+Hydrogen

Examples:

Magnesium+Nitric Acid→Magnesium Nitrate+Hydrogen

Calcium+Hydrochloric Acid→Calcium Chloride+Hydrogen

Metal Oxide+Acid→Metal Salt+Water

Examples:

Iron Oxide+Nitric Acid→Iron Nitrate+Water

Sodium Oxide+Hydrochloric Acid→Sodium Chloride+Water

Metal Carbonate→Metal Salt+Water+Carbon Dioxide

Gold Carbonate+Sulfuric Acid→Gold Sulfuric+Water+Carbon Dioxide

Potassium Carbonate+Nitric Acid→Potassium Nitrate+Water+Carbon Dioxide

Acids and Alkalis Summary

In this course of learning, we adventured through miles of new knowledge in the magical world of Chemistry. From pH Scales to Salt Equations, I was able to fully understand and present our learning in this area. Overall, I extremely enjoyed the course and is looking forward to future topics.
