. H2C2O4 aq 2NaOH aq -- Na2C2O4 aq 2H2O l arrow_forward. Oxalic acid dihydrate H2C2O4 2H2O can be used to standardize NaOH solution through acid-base titration. They vary from weak to strong acids and also are mono di or even triprotic.
Mineral acids are acids derived from inorganic compounds. The mole fraction of carbon dioxide in the resulting mixtu. A solution of oxalic acid dihydrate H2C2O4 2H2O with a known concentration of 0400 M H2C2O4 A.
To determine the molarity of an unknown NaOH solution a student weighed out 056 g of solid oxalic acid dihydrate and dissolved the solid in 328 mL of DI water. The molarity of the solution prepared by dissolving 63 g of oxalic acid H2C2O42H2O in 250 mL of water in mol L-1. Oxidation number change method ion-electron method also called the half-reaction method.
