l 100% Normal text Arial 11 B 2 | .3 | .4 5 I 6 To calculate the pH of an aqueous solution is precise know the concentration of the hydronium ion in moles per liter molarity. The pH is then calculated using the expression: pH = - log [H,O*]. 2. What is the role of the cabbage juice used in this experiment? Acids and bases are extremely important in chemical reactions. In this experiment we will use cabbage juice to help us identify many common household chemicals as acids or bases by changes in its color. 3.
