A student went to the dentist and found out that he had a cavity. He always brushes his teeth twice a day, so he didn't understand how he got a cavity. The dentist told him that drinking things every day that are acidic, such as lemonade, can contribute to cavities. He didn't drink lemonade but does drink a variety of other drinks.
The next day he brought in a sample of each drink and asked his science teacher to borrow a pH probe to test each liquid. The pH of Drink A is 11.9, Drink B is 7.0, Drink C is 5.3, Drink D is 9.8, Drink E is 2.4. Explain which drink(s) the student should avoid if he wants to protect his teeth from further damage.
In your response, be sure to include:
1. an explanation of what pH measures
2. which drinks are acidic, basic, and neutral.
