A sample of oxalic acid (a diprotic acid of the formula H2C2O4) is dissolved in enough water to make 1.00 L of solution. A 100.0 mL sample of this solution is titrated with a solution of sodium hydroxide of concentration 0.750 M and requires 20.0 mL of sodium hydroxide to reach the end point. Calculate the mass of the original oxalic acid sample.
Determine the concentration of H3O+ in a 0.064 M solution of oxalic acid, H2C2O4.H2C2O4(aq)+H2O(l) ⇌ H3O+(aq)+HC2O−4(aq) Ka1=0.054HC2O−4(aq)+H2O(l) ⇌ H3O+(aq)+C2O2−4(aq) Ka2=5.4×10−5
94.20 mL of 0.800 M potassium hydroxide reacts with 125.0 mL of a solution containing oxalic acid, H2C2O4, which is a diprotic species. What is the concentration of the acid solution?
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...
6. Oxalic acid H2C2O4 is a diprotic acid and can be used, in dilute form, as wood bleach. pKa1 = 1.237 and pKa2=4.187 A. How many milliliters of 0.0500 M NaOH would be required to completely neutralize 10.0 mL of 0.100 M H2C2O4? (5 pts) B. Estimate the pH at the first equivalence point of the titration. (6 pts) C. What is the pH at the second equivalence point of the titration. (8 pts) Please help with work shown, especially...
32.65 mL of a solution of the acid H2C2O4 is titrated, and 43.90 mL of 0.7300-M NaOH is required to reach the equivalence point. Calculate the original concentration of the acid solution.
26.24 mL of a solution of the acid H2C2O4 is titrated, and 84.20 mL of 0.4200-M NaOH is required to reach the equivalence point. Calculate the original concentration of the acid solution. How many M?
Oxalic acid, H2C204, is used in the restoration of old wood. What is the molarity of oxalic acid if 29.78 mL of 0.538 M NaOH is required to titrate a 14.75 mL of an oxalic acid solution given the following reaction? (3 decimal places, fill in the number ONLY!) H2C2O4 (aq) + 2 NaOH (aq) → Na2C204 (aq) + 2 H20 (1)
A mixture of acetic acid (CH3 CO2H monoprotic) and oxalic acid (H2C2O4; diprotic) requires 27.15 mL of 0.100 M NaOH to neutralize it. When an identical amount of the mixture is titrated, 15.05 mL of 2.68x10-2 M KMnO, is needed for complete reaction.
