1) When a sample of oxalic acid (H2C2O4), which is a diprotic acid, is titrated with 0.250 M potassium hydroxide solution, 24.44 mL of the potassium hydroxide solution are required to neutralize the acid. How many grams of oxalic acid where present in the sample?2 KOH(aq) + H2C2O4(s) ? K2C2O4(aq) + 2 H2O(l)Your answer should have 3 significant figures.
2) A sodium sulfate solution is added to a 25.0 mL sample of a solution containing Ba2+ ions until no more precipitate formed. The precipitate is collected, dried, and weighed. If 1.54 g of the precipitate are obtained, what is the concentration (in M) of Ba2+ ions in the 25.0 mL sample?
