Calcium hydroxide is an Arrhenius base. You can see that it consists of a cation (we know calcium should be a cation because it is a metal on the left side of the periodic table bonded to elements on the right side). The anions are hydroxyl groups. #Ca(OH)_2->Ca^(2+)+2OH^-#.
NaH. H3N. I know an arrhenius acid is one that yields hydrogen ions when dissolved in water--but im still confused which ones of these are arrhenius. my guess is CH4 because it would dissolve into carbon and hydrogen. but i do not know that it would dissolve into an H+.aHSO4 CH4 NaH H3N I know an arrhenius acid is one that yields hydrogen ions when dissolved in water--but im still confused which ones of these are arrhenius.
