Oxalic Acid 0.20N (0.10M)-1Lt
Oxalic Acid 0.20N (0.10M) is a standardized aqueous solution of oxalic acid used commonly as a reducing titrant or as a primary standard for standardizing oxidizing agents such as potassium permanganate. The increased concentration (compared to 0.10N) provides a stronger titrant for analytical procedures requiring higher reagent strength.
