Study Notes
Ionic Compounds
- Ionic compounds are formed by positively charged cations and negatively charged anions.
- They are usually soluble in water.
- They conduct electricity when melted or dissolved in water.
- Ionic compounds have high melting points and are hard and brittle.
- Binary ionic compounds are formed from a metal and a nonmetal.
- Multivalent ionic compounds involve transition metals with varying charges. Use Roman numerals to indicate the cation's charge.
- Naming: The cation is named first, followed by the anion. Change the anion's ending to "ide".
Covalent Compounds
- Also known as molecular compounds, covalent compounds are formed by nonmetals.
- Atoms share electrons in covalent bonds.
- Covalent compounds tend to have weaker bonds than ionic compounds.
- They are typically insoluble in water.
- They do not conduct electricity.
Chemical Reactions
- General Reaction: AC + BD → AD + BC (Example: AgNO₃ + KCl → AgCl + KNO₃)
- Combustion: A reaction where a substance reacts with oxygen to produce carbon dioxide, water, and energy.
- Example equations are provided (CH₄, C₈H₁₀, C₇H₇, C₁₂H₂₂).
- Complete combustion produces only CO₂, H₂O, and energy.
- Incomplete combustion produces a mix of CO₂, CO, C, H₂O, and energy.
Neutralization
- An acid and a base react to form a salt and water. The pH approaches 7.
- Example equations are provided (HCl + NaOH, HNO₃ + KOH).
Corrosion
- Corrosion is the breakdown of metals due to reactions with their environment.
- Corrosion can be helpful, such as forming a patina on copper that protects roofs.
- Corrosion can also be detrimental. Rust on iron weakens the metal over time.
