A student wаnted tо knоw whether аrtificiаl cytоplasm or an antacid tablet would act as a better buffer. He hypothesized that artificial cytoplasm would be a more effective buffer. To test this hypothesis, he added a specific volume of artificial cytoplasm into one test tube and the same volume of ground antacid tablet mixed with water to a second test tube. Then he added a drop of phenol red to each of the tubes. He counted the number of drops of HCl (hydrochloric acid) it took to change the color of the solution in each tube from red to yellow. If his hypothesis is correct, what should he observe?
