You are asked to calculate the $\mathrm{H}^{+}$concemaration in a solution of $\mathrm{NaOH}(\mathrm{aq})$. Because sodium hydroxide is a base, can we say there is mo $\mathrm{H}^{+}$, since having $\mathrm{H}^{+}$would imply that the solutice is acidic?

Key Concepts

Strong Base Dissociation

A strong base, such as a compound that fully dissociates in water, releases a significant amount of hydroxide ions (OH-) into the solution. Despite this, the water’s self-ionization still contributes a small amount of hydrogen ions (H+), meaning that H+ is always present even if its concentration is very low.

Water Autoionization

Water molecules naturally dissociate into hydrogen ions (H+) and hydroxide ions (OH-) even in the absence of any added acid or base. This equilibrium process means that there is always a small concentration of H+ present, regardless of whether the solution is acidic or basic.

Acid-Base Equilibrium

Acid-base equilibria involve the balance between ions in solution, particularly the interaction of H+ and OH- as dictated by the ion product constant of water (Kw). This relationship is used to calculate the concentration of one ion when the other is known, ensuring that even in basic solutions there remains a calculable amount of H+.

pH Scale

The pH scale is a logarithmic measure of hydrogen ion concentration in a solution, where a low pH indicates acidity and a high pH indicates basicity. In the context of a basic solution, the calculated pH reflects a very low concentration of H+, but it never reaches zero due to the water autoionization process.
