Substances that have a pH less than 7 are considered:
|
|
acidic
|
|
|
basic
|
|
|
neutral
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.
Detailed explanation-2: -Hence, the pH of all substances is less than 7 which denotes them as acidic in nature.
Detailed explanation-3: -Note that pH scale and proton concentration works in reverse direction, one increases so the other decreases. The pH Scale at normal room temperature is from 0 to 14 (debatable) and 7 is neutral (no excess proton or no deficiency of proton) and 0-7 is acidic (excess proton) wheras 7-14 is basic (deficiency of proton).
