Arrhenius acids are substances that, when dissolved in water, increase the concentration of the ion; bases are substances that, when dissolved in water, increase the concentration of the ion. Brnsted- Lowery acids are substances that can donate a proton ( ) to another substance; bases are substances that can accept a proton ( ). 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....
