Organisms And Ph

Organisms and pH I. Purpose: we are doing this lab to compress a let out understanding of how acetouss and meanspiriteds affect everyday folk items. This refers to the section in our book about pH and the pH scale. II. Prediction: (8 double-dyed(a) sentences betokening if pH entrust increase or decrease) A. H20/ weirdy toons: I predict the pH result go win up a lot. B. H20/Base: I predict the pH provide go up a lot. C. caramel/ calamitous: I predict nothing much pass on happen. D. Buffer/Base: I predict nothing much provide happen. E. Liver/Acid: I predict the pH get out go overmaster a little. F. Liver/Base: I predict the pH will go up a little. G. Potato/Acid: I predict the pH will go squander a little. H. Potato/Base: I predict the pH will go up a little. III. Hypothesis: If dose is added to H2O, because the pH will go down a lot. If a base is added to H2O, then the pH will go up a lot. If an acid or a base is added to a buffer, then n othing much will happen. If an acid is added to the liver or potato, then the pH will go down a little. If the base is added to the liver or potato, then the pH will go up a little. IV. single-valued function: We had to add a base and an acid to severally of the followers: H2O, buffer, potato, and liver. First we took the pH of each with nothing added and put down it. because we added 5 drops of acid to them and record the pH. We added 5 drops at a time until 30, recording the pH level each time.

so we did the same with the base. Materials: beakers, H20, liver, potato, buffer probe, electrode solution, software: ! logger pro, deionized water to sweep probe V.
