One gram equivalent of a weak acid is unable to completely neutralise one gram equivalent of a strong base.

Explanation

To solve the question "One gram equivalent of a weak acid is unable to completely neutralize one gram equivalent of a strong base," we can follow these steps:

### Step 1: Understand the Concept of Gram Equivalent
The gram equivalent of a substance is defined as the mass of that substance that can react with or replace one mole of hydrogen ions (H⁺) in a reaction. For acids, the gram equivalent is calculated as:
\[ \text{Gram Equivalent} = \frac{\text{Molar Mass}}{\text{n}} \]
where \( n \) is the number of hydrogen ions the acid can donate.
