Why did you mix 5 mL of HCL and 5 mL of NaOH to make a pH 7 solution? Explain your answer using proper equations?

Did the predicted [H+] for the solutions and the actual [H+] calculated from pH you determined with the pH meter match? If you answer is no, give possible experimental errors that could change these values?

equal quantities of a strong acid and strong base, they will neutralize each other

Explanation:

Strong acids and bases completely ionize so HCl will produce "5mL" of H+ ions and NaOH will produce "5mL" of OH- ions, thus forming HOH (water) with no excess H+ or OH- ions present, therefore pH = 7 (neutral)
