Question

pH of acetic acid is greater than dilute sulphuric acid. So, acetic acid contains ______ concentration of H⁺ ions.

विकल्प

• greater

• same

• low

Answer 1

pH of acetic acid is greater than dilute sulphuric acid. So, acetic acid contains low concentration of H⁺ ions.

Explanation:

The pH scale is inversely related to the concentration of hydrogen ions (H⁺), meaning a higher pH value corresponds to a lower concentration of H⁺ ions. Acetic acid is a weak acid that only partially dissociates in water, leaving fewer free H⁺ ions in the solution. Dilute sulphuric acid is a strong acid that dissociates completely, yielding a much higher concentration of H⁺ ions and resulting in a lower pH.
