Examples of Chemical Properties in Everyday Life

🧪 Quick Study Guide

• 🔥 Flammability: The ability of a substance to burn or ignite, causing fire or combustion. For example, propane used in BBQ grills.
• 🍎 Acidity: The level of hydrogen ions ($H^+$) in a substance. Measured on the pH scale. Lemon juice is acidic.
• ⚙️ Reactivity: How readily a substance combines chemically with other substances. Sodium reacts violently with water.
• oxidizer>Oxidation: The process of losing electrons. Rusting of iron is a common example.
• ☣️ Toxicity: The degree to which a substance can harm living organisms. Bleach is toxic if ingested.
• 🌡️ Corrosivity: The ability of a substance to destroy or irreversibly damage another surface or substance upon contact. Strong acids are corrosive.
• 💧 Solubility: The ability of a substance to dissolve in a solvent (usually water). Sugar dissolves in water.
