Like a strong acid, a strong Arrhenius base is a completely or almost completely ionized compound. Therefore, the concentration of hydroxide ions in a strong primary reaction is the same as the concentration of undissociated alkali. Common examples of stable Arrhenius bases are alkali metal and alkaline earth metal hydroxides, including NaOH and Ca(OH)2.
Formal Charge: Formal charge of an atom having more than one molecules or ions is the difference between valance electron of that atom. Short Trick to find Formal Charge – Number of valance electrons – (No. of unshared electrons + No. of bonds) Example – NH4+ Formal Charge of N = 5 –
