Question: 1 / 400

Which of these factors directly influences the basicity of a solution?

Presence of metals

Amount of hydrogen ions

The basicity of a solution is fundamentally determined by the concentration of hydroxide ions (OH⁻) relative to hydrogen ions (H⁺). The amount of hydrogen ions is crucial because it establishes the solution's pH level. In a basic solution, the concentration of hydroxide ions is greater than that of hydrogen ions. Therefore, when hydrogen ion concentration decreases, the solution becomes more basic.

A lower concentration of hydrogen ions leads to a higher pH value, and pH is inversely related to hydrogen ion concentration. Specifically, higher pH indicates a more basic solution, while lower pH indicates acidity. This relationship directly illustrates how the presence and amount of hydrogen ions impact the basicity of a solution. Understanding this interaction is key in chemistry when assessing how acidic or basic a substance is.
