Ap Chapter 16 Acid Base Equilibria Download Free Pdf Ac Strong bases are strong electrolytes and dissociate completely in solution. for example: naoh(aq) na (aq) oh–(aq) the poh (and thus the ph) of a strong base may be calculated using the initial molarity of the base. not all bases contain the oh– ion. ionic metal oxides, hydrides, and nitrides are basic. Strong bases. the most common strong bases are ionic hydroxides of the alkali metals or the heavier alkaline earth metals. (e.g., naoh, koh, and ca(oh)2 are all strong bases). memorize these. strong bases are strong electrolytes and dissociate completely in solution. for example: naoh(aq) na (aq) oh–(aq).
