Question
Which of the following gives the correct increasing order of acidicstrength?(a) Water <Acetic acid <Hydrochloric acid(b) Water <Hydrochloric acid <Acetic acid(c) Acetic acid <Water <Hydrochloric acid(d) Hydrochloric acid <Water <Acetic acid
Solution
The correct increasing order of acidic strength is (a) Water < Acetic acid < Hydrochloric acid.
Here's why:
-
Water (H2O) is a weak acid, meaning it only partially ionizes in solution.
-
Acetic acid (CH3COOH) is a stronger acid than water but is still considered a weak acid because it also only partially ionizes in solution. However, it does so to a greater extent than water.
-
Hydrochloric acid (HCl) is a strong acid, which means it completely ionizes in solution. This makes it a stronger acid than both water and acetic acid.
So, the correct increasing order of acidic strength is Water < Acetic acid < Hydrochloric acid.
