Substances are classified as acidic, basic, or neutral. The pH scale can be used to classify a substance. Which feature suggests that a substance is basic?
a
The pH is 7.
b
The pH is less than 7.
c
The pH is 0.
d
The pH is greater than 7.
d
The pH is greater than 7.
The feature that suggests that a substance is basic is answer d: The pH is greater than 7.
To determine if a substance is basic, we need to look at its pH value.
The pH scale ranges from 0 to 14, with 7 being neutral. Substances with a pH less than 7 are considered acidic, while substances with a pH greater than 7 are considered basic.
Option d) "The pH is greater than 7" suggests that a substance is basic. Therefore, d) is the correct answer.
