1. Determine the phi of 0.055 M oxalic acid (HCO, K. -5.6x 10' and K-54x 10). Note:
both steps are important here, therefore we have to set up two "ICE boxes
2. Nicotine, CHN, is a base that will accept two protons (K,7x 10, K 14x 10"). What
is the pH and the concentration of each species present in a 0.010 M solution of nicotine?
