inquiry into LiWle Laboratory Maral 15hdition Table 4.6 pH and Cells Contents pH Before Acld Conclusions: pH and Cells Enter your explanations in the last column of Table 4.6 Why would you expect cytoplasm to be as effective as the buffer in maintaining pH? Perform this procedure to test the ability of commercial products such as Alka-Seltzer, Rolaids, Tums, or antacid tablets to absorb excess H 1. Use a mortar and pestle to grind up the amount of antacid that is listed as one dose. 2 For each antacid tested, use 100 ml of phenol red solution diluted to a faint pink to wash the antacid into a 250 ml beaker. Phenol red solution is a pH indicator that turns yellow in an acid and red in a base. Use a stirring rod to get the powder to dissolve. 3. Add and count the number of 0.1 N HCI drops it takes for the solution to turn light yellow 4. Record your results in Table 4.7 Table 4.7 Effectiveness of Antacids Antacid Drops of Acid Noeded to Reach End Point Evaluation Conclusions: Effectiveness of Antacids Participate with others in concluding which of the antacids tested neutralizes the most acid. . Did a difference in dosage (convert to mg) have any effect on the results? . Which of the substances on the label could be a buffer? 4-15

Explanation / Answer

For alka seltzer 2 to 3 drop of 0.1N chl drops will be used

For rolaids the colour will changes to yellow & yellowish orange so no 0.1N HCL is being used

So the most neutralize solution of antaacid was rolaids

Yes the amount of antacids will effect this
