Finding pH From Strong Acids/Bases

Postby Labiba Sardar 2A » Sat Dec 07, 2019 9:25 am

When you have a reaction of a strong acid and a strong base, after finding how many moles H+ the strong acid makes and how many moles OH- the strong base makes, why do you have to subtract the moles of H+ from the moles of OH- to get the resulting concentration of H+?

If there is both a strong acid and a strong base then they need to be subtracted from each other, to find out what there is more of, H+ or OH-. If there are equal amounts the pH would be neutral, but once they are subtracted it is the left over H+ or OH- that did not get bounded together, thus influencing the pH.
