Lab acids bases pH scale

Lab acids bases pH scale

In this lab we will gain an understanding of:

* basic differences between the properties of acids and bases

* learn the role of hydrogen and hydroxide ions in acids and bases

* comprehend the nature of the pH scale with regards to acid and base strength.

What we will do:

* examine the effects of acids and bases on several chemical pH indicators

* determine the pH of several common household materials

* use the knowledge gained to determine the composition of unknown clear solutions.
