This reaction goes to completion because HCl and NaOH are strong acids and bases. So, all the NaOH disassociates into OH-and Na+ ions and all the HCl disassociates into Cl-and H3O+ ions. There is no limiting reactant because the HCl and NaOH are added in stoichiometric amounts. Calculate the pH Step 1: What is left in solution?

Scientists use a pH scale to measure the strength of acids and bases. The pH scale ranges from 0 to 14 . Substances with pH < 7 are acids ; the lower the pH, the stronger the acid. Substances with pH 7-14 are bases ; the higher the pH the stronger the base. Neutral solutions have a pH of exactly 7 . H O H ( ) O H (+) H
