Oh, God... this is going to take forever.

1) What color range did the substance show when tested with the indicator paper? What do your results tell you about the pH of each substance?
2) Model - Draw a diagram of the pH scale from 0-14. Show where your substances fall on the scale.
3) What general conclusions can you draw about the hydrogen ion concentration in many acids and bases found in home? (Yeah... no clue)
4) Evaluate - did you have any difficulties interpreting the results of your test? Describe possible limitations or sources of error.
