lab is to determine the effects of SDS‚ HCl‚ and NaOH on red cabbage cell membrane. Prior knowledge can tell us that the red cabbage is a red-purple color due to a pigment called anthocyanin. This is what we will be testing in the experiment. We also know that HCl is a strong acid (very low pH) and that NaOH is a strong base (very high pH). From information learned in this course (lecture/lab) we can assume that both a very high and low pH will have adverse effect on the plasma membrane. SDS (Sodium

Part I and II ● Change: You do not need to collect each chemical in test tubes. For Steps 2-8: ○ “Set up a grid on your ceramic spot plate. Add 1 or 2 drops of phenolphthalein into 1 well. Add 1 or 2 drops of methyl orange to a new well. Add 1 or 2 drops of red cabbage juice to a new well. Tear a small piece of red litmus paper and blue litmus paper and

What do you think are common properties among vinegar‚ calamansi juice‚ and soft drinks? What are common among liquid sosa (drain cleaners)‚ soaps‚ and detergents? Which among these are called acids? Which are classified as bases? In this module‚ you will investigate the properties of acids and bases using an indicator

Introduction Cabbage tree creek and its catchment runs from the foothills of Ferny Hills to Sandgate and terminates at Shorncliffe before emptying into Moreton Bay. Cabbage tree creek is known for its intact riparian and the high percentage native vegetation that lines the creek. . Cabbage tree creek is well looked after by its community‚ and is considered to be very healthy‚ with a high rating for Abiotic and biotic indicators; although it has its a few low quality zones e.g. the waterway under

Fig. 7A displays the amperometric response of Ag/ZSM-5/CPE with successive injection of OA into a stirred solution of 0.1 M NaHPO4 pH= 2 recorded at the potential of 0.73 V vs. Ag|AgCl in the concentration ranges from 16 μM to 4.0 mM. It can be seen that the aerometric current increases clearly after each injection of OA. Fabricated sensor displays the rapid response towards change in the concentration of OA which reaches a steady state within 2 s by applying the potential of 0.73 V to Ag/ZSM-5/CPE

The results of growth from day 4 to day 10 were recorded and they show that the plant grew the most in the pH of 5.6 at first but by the 10th day‚ the plant in the solution of pH 7 had grown the most and the plant in the pH 5.6 solution survived and was not far behind but the solution with pH 3 died after

factors that can cause an enzyme to slow down or to completely stop reacting. For example‚ temperature and pH can effect enzyme activity. Canned pineapple juice and fresh pineapple juice were used to see how the enzyme would react differently. In fresh pineapple juice the Bromelian have would have been denatured as it would have been in canned pineapple juice. This is because canned pineapple juice has been heated and had gone through many processes to preserve it. When the tube with water was placed
