  25. Slide 25 – acids and bases Acids – molecules that dissociates in water and releases hydrogen ions (H+). When dissociation is complete, the acid is called a strong acid. HCl  H+ and OH- H2SO4  H+ and HSO4- Bases – molecules that either takes up hydrogen ions (H+) or releases hydroxide ions (OH-). When dissociation is complete, the base is known as a strong base. NaOH  Na + and OH – Pure water is neutral since in its rare ionic form it gives off equal numbers of hydrogen and hydroxide ions. H2O  H+ and OH-
