Warm up Describe in your own words what an acid is
question Is the chemical an acid or a base and what is its pH? Calcium Chloride A. Universal Indicator Solution B. Bromothymol blue C. Sodium Hydrogen Carbonate
hypothesis Learn a little about each chemical before you make a hypothesis
Background information Calcium Chloride http://en.wikipedia.org/wiki/Calcium_chloride Universal Indicator Solution http://en.wikipedia.org/wiki/Universal_indicator Bromothymol blue http://en.wikipedia.org/wiki/Bromothymol_blue Sodium Hydrogen Carbonate http://en.wikipedia.org/wiki/Sodium_hydrogen_carbonate Now make your hypotheses (plural of hypothesis)
methods CaCl2with Univerasal Indicator Solution CaCl2with Bromothymol blue CaCl2with Sodium Hydrogen Carbonate Use other indicators if needed
results Record your observations in a data table. Draw a picture (or use a photo), and write a description
conclusion Is CaCl2an acid or a base? What is its pH? Scientifically, what is the reason for these observations?
Cool down Why is it important to understand what the properties of CaCl2are? What is a creative way you could apply what you learned in class today?
