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.
a) Write the reaction for the neutralization oxalic acid (H2C2O4) with sodium hydroxide (NaOH). Note oxalic acid is diprotic (like sulfuric acid). b) A 0.1187 g sample of an unknown, diprotic solid acid is dissolved in water. 26.36 mL of 0.1000 M sodium hydroxide is used to reach the equivalence point. How many moles of sodium hydroxide were reacted? How many moles of acid reacted? What is the molecular weight of the acid?
3. A potassium hydroxide solution was standardized against the solid acid, oxalic acid dihydrate.

The molarity of phosphoric acid in a popular cola is to be determined. A 355 mL sample of the cola is O 103 M potassium hydroxide solution. Calculate the molarity of phosphoric acid in the cola.
Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. If 37.5 mL of a sodium hydroxide solution are needed to neutralize 2.14 grams of KHP, what is the molarity of the sodium hydroxide solution? __________M Oxalic acid dihydrate is a solid, diprotic acid that can be used in the laboratory as a primary standard. Its formula...

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 201.mg of oxalic acid H2C2O4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 63.0mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide...
