Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

A student performs a titration of 31.0 mL of a phosphoric acid (H3PO4) solution of unknown concentration with a standardized 1.25 M NaOH solution. The titration requires 26.2 mL of base to reach the third equivalence point. What is the concentration of the H3PO4 solution?
d. Oxalic acid (H2C2O4) is the compound that gives rhubarb its tart flavor, and it is also a toxin when consumed in too great a quantity. If a 25.00 mL aliquot li.e. a sample) of oxalic acid (a weak acid) is titrated with an NaOH solution that is 0.1000 Mand 38.00 mL of NaOH solution is required to reach the equivalence point of the titration, determine the molarity of the oxalic acid solution. Oxalic acid has two acidic protons that will participate in the reaction (i.e. two H+ ions will dissociate from the oxalic acid molecule).
