Unit 9: Solutions, Acids, and Bases

Essential Questions:
  1. What are the properties of solutions?
  2. What are solute and solvent and what factors affect the rate of dissolving?
  3. How is solution concentration expressed in terms of Molarity and molality?
  4. How are molar and molal solutions prepared?
  5. What are colligative properties and how are they related to molal concentration for non-electrolyte solutes?
  6. What are the properties of acids and bases?
  7. Compare and contrast Arrhenius and Bronsted-Lowry acid-base theories.
  8. Describe the difference between strong and weak acids.
  9. Describe the relationship between the pH scale and the presence of hydronium and hydroxide ions in solution for acids and bases.
  10. Experimentally neutralize an acid and a base and write a balanced chemical equation to represent this reaction.
  11. Describe a titration and the function of a titration.

Alkaline battery:  http://en.wikipedia.org/wiki/Alkaline_battery

Chemistry[edit] In an alkaline battery, the negative electrode is zinc and the positive electrode manganese dioxide. The alkaline electrolyte of potassium hydroxide is not part of the reaction, only the zinc and manganese dioxide are consumed during discharge.
