The 2- and 4-sulfonates of both phenol and anisole are protonated on both the -OR (R = H, Me) and the -SO3 groups; the sulfuric acid concentrations of half-protonation have been determined to be between 80.0 and 83.3% H2SO4, corresponding with p K a's of the conjugate acids ...
Draw the conjugate acid by adding a proton (H⁺) to the base. This involves identifying the site on the base where the proton will be added, typically the site with a lone pair of electrons or a negative charge. View full solution ...
Examples of Arrhenius acids are HCl, H2SO4, and HBr. Arrhenius base examples would be NaOH, KOH, and Mg(OH)2 Is HCl gas an Arrhenius acid? HCl gas by itself is not an Arrhenius acid, but once the HCl is dissolved in water, it would then be classified as an Arrhenius acid. It is...
