Answer

Answer:

B. Bronsted - Lowry concept, C. Lewis concept

Brief Explanations:

  • Arrhenius concept: An Arrhenius acid produces $H^+$ in water. Water auto - ionizes but is not typically considered an Arrhenius acid as its main behavior is not to donate $H^+$ in the Arrhenius sense.
  • Bronsted - Lowry concept: A Bronsted - Lowry acid is a proton donor. Water can donate a proton ($H^+$) in reactions like $H_2O + NH_3\rightleftharpoons NH_4^++OH^-$, so it can act as a Bronsted - Lowry acid.
  • Lewis concept: A Lewis acid is an electron - pair acceptor. In some reactions, water can accept an electron pair, for example, when it forms hydronium ions ($H_3O^+$) by accepting a proton (which is an electron - pair acceptor), so it can act as a Lewis acid.
