Question

what are strong acids and weak acids? in the following list of acids, separate strong acids from weak acids. Hydrochloric acid, citric acid, acetic acid, nitric acid, formic acid, sulfuric acid.​

Answer 1

Answer:

In the following list of acids, separate strong acids from weak acids: Hydrochloric acid, citric acid, acetic acid, nitric acid, formic acid, sulphuric acid. Answer: In aqueous solutions, strong acids ionise completely and provide hydronium ions.

Answer 2

Answer :

Strong acid:-

• An acid that completely ionise and provide the maximum concentration of hydronium ions in an aqueous solution can be called a strong acid.
• Example of strong acids are: HBr (hydrobromic acid), HClO₄ (perchloric acid), HI (hydroiodic acid), etc.

Weak acid:-

• An acid that does not completely ionise and provides only a smaller concentration of hydronium ions in an aqueous solution can be called a weak acid.
• Examples of weak acids are: lactic acid, phosphoric acid, sulphurous acid, etc.

Strong acids:-

1. Hydrochloric acid (HCl).
2. Sulphuric acid (H₂SO₄).
3. Nitric acid (HNO₃).

Weak acids:-

1. Citric acid (C₆H₈O₇).
2. Acetic acid (CH₃COOH).
3. Formic acid (CH₂O₂).
