Acids and bases with neutral ions don't affect our pH or pOH calculations because they occur in small quantities. When neutral ions are present in a solution of an acid or base, they do not significantly contribute to the overall pH or pOH of the solution due to their low concentration.
Here's a breakdown of why neutral ions have minimal impact on pH and pOH calculations:
1. Neutral ions do not donate or accept protons like typical acids or bases. Therefore, they do not directly participate in the acid-base equilibrium that determines the pH or pOH of a solution.
2. Since neutral ions are present in small amounts relative to the acidic or basic components in a solution, their effect on the overall pH or pOH is negligible.
3. In pH and pOH calculations, the focus is primarily on the acidic and basic components that actively donate or accept protons, influencing the hydrogen ion (H+) or hydroxide ion (OH-) concentrations.
By understanding the role of neutral ions in solutions of acids and bases, we can accurately assess their impact on pH and pOH calculations and focus on the main components affecting the acidity or basicity of a solution.
