Organisms And Ph

Organisms and pH I. Purpose: we are doing this lab to lay down a let out understanding of how acetouss and meanspiriteds affect everyday sign of the zodiac 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 result increase or decrease) A. H20/ awry(p) toons: I predict the pH result go take place up a lot. B. H20/Base: I predict the pH result go up a lot. C. original/ acerb: I predict nothing much pass on happen. D. Buffer/Base: I predict nothing much go forth happen. E. Liver/Acid: I predict the pH leave alone 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 cut down 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 adde d to a buffer, then nothing 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 each of the followers: H2O, buffer, potato, and liver. First we took the pH of each with nothing added and save 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, so! ftware: logger pro, deionized water to rinse probe V.
