- 6.1: Solutions - Homogeneous Mixtures
- Mixtures in which the substances are evenly mixed together, called a homogeneous mixtures, are also called solutions. Most often we use this word to describe mixtures of something dissolved in water.
- 6.2: Solubility- Ionic Compounds
- Some ionic compounds are soluble in water. To determine whether an ionic compound is soluble, use a solubility table.
- 6.3: Solubility- Molecular Compounds
- Molecular compounds will mix if they are both polar or both non-polar. Polarity is caused by an imbalance in the way electrons are shared between atoms in the molecule.
- 6.4: Electrolytes and Nonelectrolytes
- When compounds dissolve in water, we can classify the resulting solution as electrolyte or non electrolyte depending on whether the solute dissolving creates ions (electrolytes) in solution.
- 6.5: Measures of Concentration
- To define a solution precisely, we need to state its concentration: how much solute is dissolved in a certain amount of solvent. This section defines how to calculate percentages and other concentration units for solutions.
- 6.6: Solubility - Saturated and Unsaturated Solutions
- Each substance will have a maximum amount that can dissolve in a given solvent at a given temperature. Saturated solutions are those that have this maximum amount dissolved, while unsaturated solutions have less than the maximum amount dissolved.
- 6.7: FotE - Eutrophication
- Focus on the Environment (FOTE) - When nutrients wash into waterways, this is called nutrient pollution. This can cause a chain of events called eutrophication, which can cause large die offs of aquatic organisms.
