A dark blue beaker labeled 100 millimeters Y has an arrow leading to a pale blue beaker labeled 90 millimeters H subscript 2 O. This has an arrow leading to a white beaker labeled 99 millimeters H subscript 2 O. The first arrow has a label 10 millimeters over it. The second arrow has a label 1 milliliter over it. The dark blue beaker has a box below it labeled Beaker number 1 p H = 2. The pale blue beaker has a box below it labeled Beaker number 2 p H = ?. The white beaker has a box below it labeled beaker number 3 p H = ?. If the pH of Beaker #1 is 2, then what would the best prediction for the pH of Beaker #2 be? Since 1 mL of the solution in Beaker #2 is added to 99 mL of water in Beaker #3, what would the predicted pH of Beaker #3 be? How many times greater is the concentration of H+ in Beaker #1 than in Beaker #3?
