The cubes were the following sizes: 3 cm3, 2 cm3, and 1 cm3. In the presence of an acid, such as vinegar, phenolphthalein turns from clear to pink. After ten minutes, the student cut each cube open and measured the distance that the vinegar had diffused into each cube. She then started to complete the data table.
