Unit 5: Solutions, Acids & Bases
Key Skills:
- Describe the unique role of water in chemical and biological systems
- Develop and use general rules regarding solubility through investigations with aqueous solutions
- Calculate the concentration of solutions in units of molarity
- Use molarity to calculate the dilutions of solutions
- Distinguish between types of solutions such as electrolytes and non-electrolytes and unsaturated, saturated and super saturated solutions
- Investigate factors that influence solubilities and rates of dissolution such as temperature, agitation, and surface area
- Define acids and bases and distinguish between Arrhenius and Bronsted-Lowry definitions and predict products in acid-base reactions that form water
- Understand and differentiate among acid-base reactions, precipitation reactions and oxidation-reduction reactions
- Define pH and use the hydrogen or hydroxide ion concentrations to calculate the pH of a solution
- Distinguish between degrees of dissociation for strong and weak acids and bases
