Fill in the blanks : A strong acid has a weak.......and a weak base has a strong........

Explanation

To solve the question, we need to fill in the blanks based on the concepts of acid-base chemistry, specifically focusing on the relationship between strong acids, weak acids, strong bases, and weak bases.

### Step-by-Step Solution:

1. **Understanding Strong Acids and Weak Bases**:
- A strong acid is one that completely dissociates in solution, meaning it donates all of its protons (H⁺ ions) to the solution.
- When a strong acid donates a proton, it forms its conjugate base. Since the strong acid dissociates completely, its conjugate base is relatively weak because it has a low tendency to accept protons back.
