Lab 1ADiscussion

Pre-Lab Information

• Problem/Question:– What was the question we were truly trying to

answer in this lab?• Education:– What is pH? What is it measuring?– What is a buffer?– Why are buffers important to living things?

Pre-Lab Information

• Hypothesis:– Make sure it relates to the problem/question– IF (independent variable), then (dependent variable)

• Substances:– Tap water– Egg whites– Potato– Buffer (9.0)

Substances

Order should be: Buffer > potato > egg white > tap water

• Why is potato such a good buffer? It grows in the ground, so will see a lot of harsh conditions (variations in pH due to rain, soil, pollution, etc.)
