NOTE: translucent (positive for fats) and opaque (negative for fats) To test for lipids, when we put one drop of corn oil on a paper towel (positive control): what opacity (translucent or opaque) did you observe in the paper towel? Does that mean the substance is present or absent? To test for lipids, when we put one drop of distilled water on a paper towel (negative control): what opacity (translucent or opaque) did you observe in the paper towel? Does that mean the substance is present or absent? What is the purpose of having controls when testing for lipids in this experiment?
The pH scale shows availability of reactive hydrogen ions (H+) in a liquid. The scale is logarithmic, so milk has 10 times as many H+ ions as pure water, for a given volume. How many more H+ ions does soda pop have compared to pure water? Write the number only.
What is good hypothesis, when testing for the presence of a starch?
