Chem. 151 – Chapter 4, sections 1-3 and 8 Reading Objectives

1. Understand what occurs when an ionic substance dissolves in water, including what is meant by hydration of ions. Know the meaning of the term solubility. Understand how some non-ionic substances can also dissolve in water

2. Be familiar with the parts of a solution – solute and solvent. Understand how the electrolytic nature of a solution is affected by the types of solute particles. (Note: we will discuss section 2 in more detail toward the end of the semester in conjunction with chapter 11).

3. Be able to perform calculations involving molar concentrations for solutions, including calculation of molarity, calculating ion concentration from solution concentration, calculating the volume required to obtain a specific amount of solute, and calculating the mass of solute required to make a solution of a specific concentration.

4. Be able to perform calculations involving dilutions of solutions.

5. Be able to perform stoichiometry calculations involving solutions by using molarities and volumes.

6. Understand what is meant by the following terms: acid, base, neutralization, titration, indicator, buret, equivalence point, end point, standard solution, standardization.

7. Be able to perform calculations involving titrations.
