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
