▁provide ▁a ▁mole c ule ▁with ▁basic ▁properties . ▁Car bon ▁can ▁act ▁as ▁a ▁base ▁as ▁well ▁as ▁nit ro gen ▁and ▁o xygen . ▁Fl u or ine ▁and ▁sometimes ▁rare ▁g ases ▁possess ▁this ▁ability ▁as ▁well . ▁This ▁occurs ▁typically ▁in ▁comp ounds ▁such ▁as ▁but yl ▁l ith ium , ▁alk ox ides , ▁and ▁metal ▁am ides ▁such ▁as ▁sod ium ▁am ide . ▁B ases ▁of ▁carbon , ▁nit ro gen ▁and ▁o xygen ▁without ▁reson ance ▁stabil ization ▁are ▁usually ▁very ▁strong , ▁or ▁super b ases , ▁which ▁cannot ▁exist ▁in ▁a ▁water ▁solution ▁due ▁to ▁the ▁acid ity ▁of ▁water . ▁Res on ance ▁stabil ization , ▁however , ▁enables ▁we aker ▁bases ▁such ▁as ▁car box yl ates ; ▁for ▁example , ▁sod ium ▁ac et ate ▁is ▁a ▁weak ▁base . ▁ ▁Str ong ▁bases ▁A ▁strong ▁base ▁is ▁a ▁basic ▁chemical ▁comp ound ▁that ▁can ▁remove ▁a ▁pro ton ▁( H +) ▁from ▁( or ▁de pro ton ate ) ▁a ▁mole c ule ▁of ▁even ▁a ▁very ▁weak ▁acid ▁( such ▁as ▁water ) ▁in ▁an ▁acid - base ▁reaction . ▁Common ▁examples ▁of ▁strong ▁bases ▁include ▁hydro x ides ▁of ▁alk ali ▁met als ▁and ▁al kal ine ▁earth ▁met als , ▁like ▁Na OH ▁and ▁, ▁respectively . ▁Due ▁to ▁their ▁low ▁sol ub ility , ▁some ▁bases , ▁such ▁as ▁al kal ine ▁earth ▁hydro x ides , ▁can ▁be ▁used ▁when ▁the ▁sol ub ility
