      The chemically active part of an acid is HYDROGEN IONS (H+), hydrogen atoms without their electron, basically a naked protons, albeit they quickly combine with a water molecule to form hydronium ions (H3O+). The chemically active part of a base is  HYDROXYL IONS (OH), bonded oxygen and hydrogen pairs of atoms each with an extra electron. Note that H+ and OH readily combine to form H2O. Hence bases neutralize acids and vice versa. The following animated video explains acids and bases further:
