How does pH relate to hydroxide ion concentration in a solution?

Explanation:
The relationship between pH and hydroxide ion concentration can be understood through the concepts of acidity and basicity in aqueous solutions. The pH scale is a measure of the hydrogen ion (H⁺) concentration; lower pH values indicate higher concentrations of H⁺ ions, while higher pH values indicate lower concentrations of H⁺ ions. The pOH of a solution is defined as the negative logarithm of the hydroxide ion (OH⁻) concentration. Since pH and pOH are related by the equation: pH + pOH = 14 (at 25 degrees Celsius), it follows that as pH increases (indicating lower H⁺ concentration), pOH must decrease (indicating higher OH⁻ concentration), and vice versa. Therefore, as the pH decreases, the hydroxide ion concentration increases, illustrating an inverse relationship. This means that when the pH of a solution is low, the concentration of hydroxide ions is low as well. Conversely, a high pH indicates a higher hydroxide ion concentration. Thus, it is accurate to say that pH is inversely proportional to hydroxide ion concentration, which confirms the correctness of the chosen answer. Understanding the interplay between pH and
