Question

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.

Answer 1

Ph measures how acidic or basic something is. The lower the number the more acidic it is going to be.

Drink A is basic, he can drink that

Drink B is neutral, he can drink that

Drink C is acidic, he should avoid

Drink D is basic, he can drink that

Drink E is acidic, he should avoid
