Pre-lab Review - Experimental Design Week 2
Prepare for Laboratory
1. Review the following textbook section(s)
1.2 – Scientific Method: Thinking Like a Scientist
10.1 – Acids and Bases
10.2 – Strengths of Acids and Bases
10.5 – The pH Scale
10.6 – Reactions of Acids and Bases
10.7 – Buffers
2. Review the Lab Procedure and other documents posted online.
3. Be able to work the following textbook problems.
Acids and bases: 10.1
Strengths of acids and bases: 10.15
pH: 10.37

d. Write the definition of a base.
e. Write the definition of an enzyme.
f. Briefly describe the scientific method.
g. Draw a diagram that shows the steps of the scientific method and how they relate to each
other.
h. Write the equation used to calculate the concentration of a diluted solution.
i. Name the three reagents used for chemical pretreatment.
