What is true about a solution if it has a higher concentration of hydroxide ions?
The more basic the solution
The more acidic the solution
The more hydroactive
The more radioactive the solution
The correct answer is: The more basic the solution
A solution with a higher concentration of hydroxide ions indicates that it is more basic. In chemistry, the pH scale is used to measure how acidic or basic a solution is, with values below 7 being acidic, 7 being neutral, and above 7 being basic. Hydroxide ions (OH⁻) contribute to the basic nature of a solution, as they can neutralize hydrogen ions (H⁺), which are responsible for acidity. When the concentration of hydroxide ions increases, it results in a decrease in the concentration of hydrogen ions, leading to a higher pH value. This relationship is a fundamental concept in acid-base chemistry, reinforcing the idea that a greater presence of hydroxide ions correlates with increased basicity of the solution. In contrast, solutions with higher concentrations of hydrogen ions would be more acidic, and terms like "hydroactive" or "radioactive" do not pertain to this context. The focus here is on the acid-base properties governed by the concentrations of H⁺ and OH⁻ ions.
