Fill in the blanks by using the correct word/term given in the brackets.
The hydrogen ion concentration of a solution with pH = 3 is _____ than the solution with pH = 6. (greater/less)

Explanation

To solve the question, we need to compare the hydrogen ion concentrations of two solutions with different pH values: one with a pH of 3 and the other with a pH of 6.

### Step-by-Step Solution:

1. **Understanding pH and Hydrogen Ion Concentration**:
The pH of a solution is related to the concentration of hydrogen ions (H⁺) in that solution. The formula that relates pH to hydrogen ion concentration is:
\[
\text{pH} = -\log[H^+]
