Question

Which of the following is an example of weak acid?
A) Hydrochloric acid.
B) Acetic acid.
C) Sulfuric acid.
D) Ammonium hydroxide.

Answer 1

We know that an acid that partly dissociates into its ions in an aqueous solution are called weak acids; on the contrary, a strong acid completely dissociates into its ions in water. The weak base is a conjugate base of a weak acid, whereas the conjugate acid of a weak base is a weak acid.

Complete step by step answer:
We have to remember that the acetic acids, otherwise called Ethanoic acids, are a weak acid. The chemical formula of acetic acid is$C{H_3}COOH$. It is known to be the dynamic part of vinegar, which is an $4\% -7\%$ arrangement of acidic acids in water. Acetic acid is a powerless acid since it possibly halfway separates into its constituent particles when broken down in water. Notwithstanding, it is imperative to take note that concentrated acidic acids are known to be destructive to human skin.
Therefore, the option B is correct.
We must remember that hydrochloric acid and Sulfuric acid are strong acids. Hence option A and C are incorrect.
We also know that the ammonium hydroxide is a base hence option D is incorrect.

So, the correct answer is Option B.

Additional information:
We have to remember that the molar mass of acidic acids relates to $60.052$ grams per mole. Under standard conditions for temperature and weight, this acid exists as a dreary fluid that exudes a solid, vinegar-like smell. In its fluid express, the thickness of acidic acids is equivalent to $1.049$ grams per cubic centimeter. Despite, strong acidic acids are known to have a moderately more noteworthy thickness, equivalent to $1.27$ grams per cubic centimeter. This weak acid is known to shape miscible combinations with water. The form base of acidic acids is usually alluded to as acetic acid derivation.

Note: We realize that the Buffer Solutions are water dissolvable based arrangements which contains a combination of a frail corrosive and the form base of the feeble corrosive, or a powerless base and the form corrosive of the feeble base. Cradle arrangement opposes a change in upon weakening or upon the expansion of limited quantities of corrosive/soluble base to them.
