A solution contains equal concentrations of hydrochloric acid (HCl) and sodium hydroxide (NaOH). HCl is a strong acid that dissociates completely in water to release protons (H+), while NaOH is a strong base that dissociates completely to release hydroxide ions (OH-). Consider the following questions about the pH of this solution:
What will be the pH of the resulting solution after mixing the hydrochloric acid and sodium hydroxide in equal concentrations?
