Question
What is the most likely pH of a tube of toothpaste?
- 3
- 5
- 7
- 10
Hint:
pH of toothpastes are generally on the basic side.
The correct answer is: 10
The pH of the toothpaste can generally range from 7 to 10, depending on its additives.
Toothpastes are usually weakly basic in nature. PH of saliva is 7.4, which is basic too. An acidic environment will cause teeth enamel to corrode, and will ultimately weaken them.
pH of toothpastes are generally 10.
