Oxalic acid has the ability to form strong bonds with various minerals, such as sodium, potassium, magnesium, and calcium. When this occurs, the compounds formed are usually referred to as oxalate salts. Thus, “oxalate” usually refers to the salt forming ion of oxalic acid.

Is oxalate the same as oxalic acid?
Oxalic acid is an organic compound found in many plants. These include leafy greens, vegetables, fruits, cocoa, nuts and seeds ( 1 ). In plants, it's usually bound to minerals, forming oxalate. The terms “oxalic acid” and “oxalate” are used interchangeably in nutrition science.
What is oxalate used for?
Calcium oxalate is used in the production of ceramics, while strontium oxalate and barium oxalate are used as reducing agents in laboratory chemistry and pyrotechnics. Other oxalates used as chemical reagents include potassium hydrogenoxalate, also known as salt of sorrel, due to its occurrence in the sorrel plant.
Why is sodium oxalate used instead of oxalic acid?
An organic sodium salt consisting of sodium and oxalate ions in a 2:1 ratio. Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na2C2O4. ... Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions.
Is oxalic acid harmful to humans?
Oxalic acid is toxic because of its acidic and chelating properties. It may cause burns, nausea, severe gastroenteritis and vomiting, shock and convulsions. It is especially toxic when ingested. As little as 5 to 15 grams (71 mg/kg) may be fatal to humans.
Are eggs high in oxalate?
The only fruits to worry about are raspberries because no one puts oranges on their yogurt. Bananas, peaches, blueberries and strawberries are perfect toppings. More trouble, but no oxalate, eggs any way at all.
How do you flush out oxalates?
Drinking plenty of water to help your body flush oxalates out. Consuming enough calcium, which binds to oxalates during digestion. Limiting sodium and sugar intake, which may contribute to kidney stones at high levels. Getting the recommended amounts of vitamin C — too much can increase oxalic acid production in your ...
What are symptoms of high oxalates?
Signs and symptoms of oxalate toxicity can include:
- Pain, muscle aches & fatigue.
- Joint pain – if deposition of oxalate crystals is in synovial fluid or connective tissue.
- Strange rashes.
- Kidney Stones.
- Chronic UTIs, interstitial cystitis or kidney infections.
- Frequently cloudy or hazy urine.
- Vulvar pain in women.
What foods have no oxalates?
Eating Guide

Why do we standardize potassium permanganate with oxalic acid before titration?
Thus, KMnO4 serves as self indicator in acidic solution. Potassium permanganate is standardized against pure oxalic acid. It involves a redox reaction. Oxalic acid is oxidised to carbon dioxide by KMnO4, which itself gets reduced to MnSO4.
Why Oxalic acid is primary standard?
A primary standard is some substance such as oxalic acid which can be precisely weighed out in pure form, so that the number of moles present can be accurately determined from the measured weight and the known molar mass. ... The standard solutions used in an acid-base titration need not always be primary standards.
Is oxalate a salt?
Thus, “oxalate” usually refers to the salt forming ion of oxalic acid. Although both sodium and potassium oxalate salts are water soluble, calcium oxalate is practically insoluble (8.76x10−8 mol/L at 37°.
