Answer questions a-c about the Bronsted acid-base reaction below using the identifying letters A-D below each structure. A table of pKa values for various organic and inorganic acids can be found in the references section. a) The weaker acid is b) Its conjugate base is c) The species that predominate at equilibrium are (two letters, e.g. AC) Answer questions a-c about the Bronsted acid-base reaction below using the identifying letters A-D below each structure. The pKa's for the acids of interest are: hydrogen cyanide (pKa=9.3), and hydronium ion (pKa=1.7). a) The stronger base is b) Its conjugate acid is c) The species that predominate at equilibrium are (two letters, e.g. ac)
