There are three ways in which to define acids and bases: the arrhenius concept, the brønsted-lowry concept, and the lewis concept. arrhenius acids are substances that, when dissolved in water, increase the concentration of the h+ ion; arrhenius bases are substances that, when dissolved in water, increase the concentration of the oh− ion. brønsted-lowry acids are substances that can donate a proton (h+) to another substance; brønsted-lowry bases are substances that can accept a proton (h+). a lewis acid is an electron-pair acceptor, and a lewis base is an electron-pair donor. part a using the arrhenius concept of acids and bases, identify the arrhenius acid and base in each of the following reactions: 2koh(aq)+h2so4(aq)→k2so4(aq)+2h2o(l ) nh3(g)+hcl(g)→nh4cl(s)
