Question

Sodium hydroxide relaxers have an alkaline pH of:

A) 1-3
B) 4-6
C) 7-8
D) 10-14

Answer 1

Sodium hydroxide relaxers have a high pH value because NaOH is a strong base, and their pH is in the range of 10-14, making them highly alkaline.

Step-by-step explanation:

The student's question is about the pH level of sodium hydroxide relaxers. Sodium hydroxide (NaOH) is a strong base, which means it has a high pH value. The pH scale ranges from 0 to 14, with 7 being neutral. Anything below 7 is acidic, and anything above 7 is alkaline or basic. Sodium hydroxide solutions, being highly alkaline, typically have a pH that is much higher than 7. Therefore, the correct answer to the question is D) 10-14, indicating that sodium hydroxide relaxers have an alkaline pH.
