Question

In terms of acidic strength, which one of the following is in the correct increasing order?
(a) Water < Acetic acid < Hydrochloric acid
(b) Water < Hydrochloric acid < Acetic acid
(c) Acetic acid < Water < Hydrochloric acid
(d) Hydrochloric acid < Water < Acetic acid

Answer 1

Answer:

option c is the correct answer

Answer 2

In terms of acidic strength, the increasing order is as follows-

Water < Acetic acid < Hydrochloric acid.

• Hydrochloric acid or HCl is a very strong acid and it has a pH near about 2. It easily releases its hydrogen ion.
• Acetic acid is a weak acid having higher pH in the acidic range. It can also release its hydrogen ion and show an acidic character.
• Water is a neutral substance. It has a pH of 7.
• Thus, the acidic order is as follows-
• Water < Acetic acid < Hydrochloric acid.
• Hence the correct option is a.
