Explanation

## Step1:When solutions of hydrochloric acid (HCl) and sodium hydroxide (NaOH) are reacted together in exact quantities so that both are completely reacted, an acid-base reaction will take place. ### ## Step2: This reaction is commonly known as neutralization because the solution will become neutral. In a neutral solution, the concentration of hydrogen ions ( ) equals the concentration of hydroxide ions ( ).## Step3:The resulting product of this reaction, water (H₂O), is a neutral substance, and NaCl formed is a salt that also doesn't influence the nature of solution in terms of acidity or alkalinity. ## Step4:pH is a measure of how acidic or basic a solution with value 0 being highly acidic and 14 being highly basic. pH of 7 indicates a neutral solution.## Step5:Since both reactants are present in exact quantities for neutralizing condition, the reaction will result in a neutral solution, it means the pH will be ______ attract for ) is one mechanism through which a plan, such as bookstore on its activity.
