Question

Toothpaste has pH value

• A. 7
• B. 7.5
• C. 6.5
• D. 9

Answer 1

The correct option is D

9

The explanation for the correct option (D):

• pH refers to the potential of Hydrogen (H).
• pH is used to determine the acidic or basic strength of the solution.
• When the pH of the solution is less than 7, the solution is said to be acidic. The pH value greater than 7 indicates that the solution is basic while the neutral solution has a pH value of 7.
• Most of the toothpaste consists of bases in order to neutralize the mouth acid. Hence, the pH value of toothpaste is 9.

Final Answer: Hence, option (D) is correct. Toothpaste has a pH value of 9.
