▁are ▁also ▁strong ▁bases ▁since ▁they ▁dis soci ate ▁completely ▁in ▁water . ▁Gu an id ine ▁is ▁a ▁special ▁case ▁of ▁a ▁species ▁that ▁is ▁exception ally ▁stable ▁when ▁pro ton ated , ▁analog ously ▁to ▁the ▁reason ▁that ▁makes ▁per ch lor ic ▁acid ▁and ▁sul fur ic ▁acid ▁very ▁strong ▁ac ids . ▁ ▁Ac ids ▁with ▁a ▁p ▁Ka ▁of ▁more ▁than ▁about ▁ 1 3 ▁are ▁considered ▁very ▁weak , ▁and ▁their ▁conjug ate ▁bases ▁are ▁strong ▁bases . ▁ ▁Super b ases ▁ ▁Group ▁ 1 ▁sal ts ▁of ▁car ban ions , ▁am ides , ▁and ▁hyd rides ▁tend ▁to ▁be ▁even ▁stronger ▁bases ▁due ▁to ▁the ▁extreme ▁weak ness ▁of ▁their ▁conjug ate ▁ac ids , ▁which ▁are ▁stable ▁hydro car b ons , ▁am ines , ▁and ▁di h ydro gen . ▁Usually , ▁these ▁bases ▁are ▁created ▁by ▁adding ▁pure ▁alk ali ▁met als ▁such ▁as ▁sod ium ▁into ▁the ▁conjug ate ▁acid . ▁They ▁are ▁called ▁super b ases , ▁and ▁it ▁is ▁impossible ▁to ▁keep ▁them ▁in ▁water ▁solution ▁because ▁they ▁are ▁stronger ▁bases ▁than ▁the ▁hydro x ide ▁ion . ▁As ▁such , ▁they ▁de pro ton ate ▁conjug ate ▁acid ▁water . ▁ ▁For ▁example , ▁the ▁eth ox ide ▁ion ▁( the ▁conjug ate ▁base ▁of ▁eth an ol ) ▁in ▁the ▁presence ▁of ▁water ▁under go es ▁this ▁reaction . ▁▁ ▁+ ▁ ▁→ ▁ ▁+ ▁▁ ▁Ex amples ▁of ▁common ▁super b ases ▁are : ▁But
