Question

In the following list of acids, separate strong acids from weak acids :

[Hydrochloric acid, Citric acid, Acetic acid, Nitric acid, Formic acid, Sulphuric acid.]

• A. Weak acids $\to$ Citric acid, Formic acid, Acetic acid
  Strong acids $\to$ Hydrochloric acid, Nitric acid, Sulphuric acid
• B. Weak acids $\to$ Hydrochloric acid, Formic acid, Citric acid
  Strong acids $\to$ Nitric acid, Sulphuric acid, Acetic acid
• C. Weak acids $\to$ Acetic acid, Nitric acid, Sulphuric acid
  Strong acids $\to$ Citric acid, Formic acid, Hydrochloric acid
• D. Weak acids $\to$ Hydrochloric acid, Nitric acid, Sulphuric acid
  Strong acids $\to$ Citric acid, Formic acid, Acetic acid

Answer 1

Answer: (A)

Weak acids $\to$ Citric acid, Formic acid, Acetic acid

Strong acids $\to$ Hydrochloric acid, Nitric acid, Sulphuric acid

Strong Acid: Strong acids ionize completely in their aqueous solution and produce a maximum number of hydrogen ions. Mineral acids are generally strong acids.

Weak Acid: Weak acids do not ionize completely in their aqueous solution. Organic acids are generally weak acids.

Strong acid: Hydrochloric acid, Nitric Acid, Sulphuric Acid

Weak acid: Citric Acid, Acetic Acid, Formic Acid

So, the correct option is $A$
