Before the break, we looked at acids and alkalis (bases in solution) and how to measure their strength with indicators and the pH scale.
Here is a text that talks about this information.

Page 2 (read this too)
Page 3 (answer the questions in the box on the left, writing the answers in your notebook please)
Now, watch a Brainpop video by logging into Drive and accessing Brainpop from the menu. Then go to the video on pH scale and complete the quiz after the video.
IF you have time, go to the Acids and Bases video and do that quiz as well.
There is also cool interactive ‘lab’ that you click through under games. Search for pH. It comes in two parts – you do the pH scale and calibration part first, and then the Acidifying Salsa part. This may be helpful for our next lab.
