Let's do our first lab!
Hand out 'The pH of Common Substances' (25 points)
Make a data table for your findings on back of lab sheet.
3 vertical columns, 6 horizontal rows. (see my example)
In the data table and based on what you know about pH of some common substances, make predictions about expected pH levels of the 5 mystery substances and write them in your data table along with what you think the substance is.
Lab groups will come up one at a time to get pH paper and put one drop of the substances on strips of pH paper. Carefully take the dish of pH paper and substances back to your table.
Google: pHydrion papers 1 to 12 for pH scale
Compare the color of your pH paper to the scale and record your best estimate for pH for the substances. Lab results photo here!
Finish lab sheet with group and turn in! 25 pts
