Questions: When looking at an aqueous solution of a weak base, a higher pH corresponds to: Select the correct answer below: a higher concentration of hydronium a less concentrated solution a higher concentration of hydroxide a more dilute solution

Solution Steps

The pH of a solution is a measure of its acidity or basicity. For a weak base in an aqueous solution, a higher pH indicates a more basic solution.

In a basic solution, the concentration of hydroxide ions (\(\text{OH}^-\)) is higher. Since pH is inversely related to the concentration of hydronium ions (\(\text{H}_3\text{O}^+\)), a higher pH means a lower concentration of hydronium ions and a higher concentration of hydroxide ions.

• A higher concentration of hydronium: This would correspond to a lower pH, not a higher pH.
• A less concentrated solution: This does not directly relate to pH.
• A higher concentration of hydroxide: This is consistent with a higher pH.
• A more dilute solution: This does not directly relate to pH.
