How are ions related to acids and bases
WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + … WebAccording to Lewis, an acid accepts a pair of electrons and a base donates a pair of electrons during a reaction. Hydronium Ion (H3O+) The ion that forms when a water molecule gains a hydrogen ion Conjugate Acid The ion or molecule formed when a base gains a hydrogen ion Conjugate Base
