1. Should the calcium oxalate solution be made acidic or basic to achieve the MINIMUM amount of precipitate? Provide an explanation and use the following chemical equations and your experimental evidence to help you answer the question. C2042- (aq) + H+ (aq) →HC204 (aq) HC2O4 (aq) + H+ (aq) → H2C204 (aq) 2. A. After adding the ammonia to the oxalic acid solution, was the precipitate calcium oxalate or calcium hydroxide? B. How can you prove this? Include your own experimental evidence. C. Where would hydroxide ions come from to form the hydroxide precipitate? (A chemical reaction is necessary). 1.
