Question

Q5. What are strong 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, sulphuric acid.​

Answer 1

$\huge\sf\red{Answer}$

$\large\underline{\sf{\pink{Strong \ Acid}}}$

➝ A stron acid is an acid that provide the maximum concentration of Hydronium Ions($\sf {H}^{+}$) in an aqueous solution.

$\large\underline{\sf{\green{Weak\ Acid}}}$

➝ A weak acid is an acid that provides only a smaller concentration of Hydronium Ions($\sf {H}^{+}$) in an aqueous solution.

Answer 2

Answer:

Strong acid: A strong acid is an acid that provides the maximum concentration of Hydronium Ions(H+) in an aqueous solution.  

Weak acid: A weak acid is an acid that provides only a smaller concentration of Hydronium Ions(H+) in an aqueous solution.

Examples of strong acids:

Hydrochloric acid (HCl)

Sulphuric acid (H₂SO₄)

Nitric acid (HNO₃)

Examples of weak acids:

Citric acid (C₆H₈O₇)

Acetic acid (CH₃COOH)

Formic acid (CH₂O₂)
