1. The problem statement, all variables and given/known data Oxalic acid, H2C2O4, which is found in certain pants, can provide two hydronium ions in water. Write balanced equations to show how oxalic acid can supply one and then a second H3O+ ion. 2. Relevant equations There's not really an equation, and if there is please don't make me feel stupid. 3. The attempt at a solution I don't really even know how to start.
