Identifying Acid and Base Components

Two aqueous solutions are described below (1 & 2). From the list at the bottom select molecules and ions that could function as acids or bases in these solutions, and enter letters identifying your selections in the appropriate answer box. Assume that the hydroxide ion concentration in the sulfuric acid solution and the hydronium ion concentration in the ammonia solution are both negligible.
Do not enter superfluous characters, since they will be counted as incorrect answers.
