The term strong and weak acids is used to indicate the
- number of H\(^+\) released by an acid
- number of OH\(^-\) released by an acid
-
extent of ionization of an acid
- strength of its action on substance
The correct answer is: C
Explanation
The terms "strong" and "weak" are used to describe the extent to which an acid dissociates into ions in an aqueous solution.
-
Strong acid: An acid that completely dissociates into ions in water. For example, hydrogen chloride (HCl) is a strong acid because it ionizes completely into hydrogen ions and chloride ions in water.
-
Weak acid: An acid that only slightly dissociates into ions in water. For example, acetic acid is a weak acid because it only dissociates about 5% into ions in water
