Acid
A substance that has a pH of 0<x<7 and donates protons (H+ ions).
Base
A substance that has a pH of 7<x<14 and accepts protons (OH- ions).
Strong Acid
An acid that completely dissociates in an aqueous solution (e.g., Hydrochloric Acid).
Weak Acid
An acid that partially dissociates in an aqueous solution (e.g., Ethanoic Acid).
pH Scale
A scale used to measure how acidic or basic a solution is, ranging from 0 to 14.
Saturation of Solution
The point at which no more solute can dissolve in the solvent; confirmed by crystallization.
Indicator
A substance that changes color in response to pH changes, used to determine acidity or basicity.
Hydrated Substance
A substance that is chemically combined with water.
Anhydrous Substance
A substance that does not contain any water.
Water of Crystallisation
Water molecules that are present in hydrated crystals.
Reaction with Metal Carbonates
Acid + Metal Carbonate → Salt + CO2 + H2O.
Reaction with Metals
Acid + Metal → Salt + Hydrogen.
Preparation of Salts
Can occur by reacting acids with metals, insoluble bases, soluble bases, or carbonates.
Solubility Rules For Salts
Guidelines that determine whether a salt will dissolve in water.
Acid + Base Reaction
Acid + Base → Salt + Water.
Acidic Oxides
Oxides that react like acids, examples include SO₂ and CO₂.
Basic Oxides
Oxides that react like bases, examples include CuO and CaO.
Titration
A method used to prepare salts by neutralizing an acid with a base.
Amphoteric Oxides
Oxides that can act as both acids and bases depending on the reactants.
Examples of Amphoteric Oxides
Al₂O₃ and ZnO.
