Oxalic acid, H2C2O4 has a pKa1 of 1.25 and a pKa2 of 4.14. When sodium hydrogen oxalate is put into water, will the solution be acidic, basic, or neutral? Justify your answer with some equations and calculations and words.
A solution is prepared by dissolving 0.5892 g oxalic acid (H2C2O4) in enough water to make 100.0 mL of solution. A 10.00-mL aliquot (portion) of this solution is then diluted to a final volume of 250.0 mL. What is the final molarity of the diluted oxalic acid solution? I do not know if the answer of 0.00187 or 1.87 x 10^ -3 is correct. It is incorrect in my perspective, so i do not expect that answer, if you think...
4. Calculate the mass of Oxalic acid (H2C2O4*2H2O) required to neutralize 20.0 ml of 0.10 M NaOH solution using the balanced chemical equation for this reaction. 5. A 0.120 g sample of pure oxalic acid (H2C2O2*2H2O) was dissolved in water and neutralized with 21.0 ml of NaOH. Calculate the molarity of NaOH. Do not use scientific notation, but do use the proper number of significant digits and units.
