Look for at least 3 acids and at least 3 bases around your home. Remember that acids have a pH level lower than 7, pH 7 is neutral, and bases have a pH level higher than 7.
Three examples of acids that I found in my home are: __________________________________________________________________
Describe each of the three acids using complete sentences. Some suggestions…what do they contain, what they are used for and why, what are their properties, what is their pH? 1.2.3.
Describe the common attributes of acids:

Part III – Short Answers: Answer the following questions in short-answer format (3–5 detailed sentences each).
Look at your data for the three lakes in the virtual lab. Acid rain is impacting two of these three lakes. Answer the questions below to explain how the location of each lake relates to its pH level.
What is acid rain?
Which two lakes from the virtual lab are receiving acid rain?
Discuss how the location of each lake (Lake 1, Lake 2, and Lake 3) relates to its pH level. Include some of the impacts of acid rain. Use data from Part 1, including what you observed on the signs for each lake, to justify your points.
Imagine that a lake receives acid rain for an extended period of time. The original pH of the lake was 6, but it has now dropped to pH 3. How many times more acidic has this lake become? Watch this resource video for help: https://www.youtube.com/watch?v=Nf8cuvl62Vc
What negative impacts can this amount of acidification have on the environment?
