About This Chapter
Compounds & Concentration - Chapter Summary
This chapter goes over chemical compounds and concentrations. You'll get clear definitions of Raoult's law and learn how ionic compounds are formed and named. Self-assessment quizzes are included to help you check your understanding of important scientific concepts as you work through each lesson. If you get stuck, you can reach out to our expert instructors who are happy to help you. Navigating the course is simple and easy with our intuitive dashboard, and interactive video timelines allow you to quickly find the information you need to learn or review. These lessons will teach you things like:
- What Raoult's law states and how it relates to colligative properties
- How molarity and molality concentration is calculated
- The names and formation of ionic compounds
1. Colligative Properties and Raoult's Law
Learn why vapor pressure and osmotic pressure are colligative properties. With examples, discover how to apply Raoult's Law and learn the formula to find osmotic pressure.
2. Calculating Molarity and Molality Concentration
Molarity is defined as moles of solute per liter of solution and is often used to calculate solutions in stoichiometry. Molality is moles of solute per kilogram of solvent, which is used in calculating boiling point and freezing point. Learn about when to use molarity and molality and how to uncover unknown variables through their equations.
3. Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds
An important part of dealing with chemical compounds is knowing how to refer to them. Learn how to name all ionic compounds, including simple binary compounds, compounds containing transition metals and compounds containing polyatomic ions.
4. Ionic Compounds: Formation, Lattice Energy and Properties
Most of the Earth's rocks and minerals are ionic compounds. Learn the definition of an ionic compound, explore its formation and properties, and discover how lattice energy makes iconic compounds stronger.
