How can you tell if a substance is amphiprotic using the acid/base table? List as many amphiprotic substances as you can find on the table. For one of those substances, give an example of that substance acting as an acid, and an example of it acting as a base: Notice that all amphiprotic substances (except for H2O), are polyatomic groups that contain at least one proton and are negatively charged. In a reaction between two amphiprotic substances in aqueous solution, how can you use your table to find out which substance will act as the acid and which will act as the base? Practice: Using your table, label each reactant as an acid or base, and determine the products. Then label each product as an acid or base (look at the reverse reaction). 1. HCO3- + H2PO4- 2. HPO42- + HSO4- 3. H2O + HSO3- HCO3- + HSO4- Assignment 3: Hebden p.117 #12 & read p.117 & 118 & do p.119 #13, 14
