Oxalic Acid Formula
Oxalic Acid Formula
Oxalic Acid Formula is also called as ethanedioic acid. In nature and structure, it is a strong dicarboxylic acid. Oxalic Acid Formula is a naturally occurring organic acid found in plants and vegetables. It is also produced in the body by the metabolism of ascorbic acid and glyoxylic acid. This acid has many uses. The most important are applications in the detergent industry such as washing, bleaching and dyeing. On the Extramarks website, descriptive examples will be provided to illustrate the formula of oxalic acid.
What is Oxalic Acid?
Oxalic Acid Formula is one of the organic compounds found in various vegetables and plants. It is a powerful dicarboxylic acid and is also toxic. It is the simplest dicarboxylic acid, containing only two carboxylic acid groups directly bonded to each other at the carbon atom, namely (COOH).
Equivalent Weight of Oxalic Acid (Calculation)
Equivalent weight = (molecular weight)/(moles equivalent)
One mole of oxalic acid can release 2 moles of H+ ions and neutralize 2 moles of OH- ions, so the number of equivalent moles here equals 2. Therefore, the equivalent weight of Oxalic Acid Formula can be calculated as:
Equivalent mass of oxalic acid = molecular weight of oxalic acid/2 = 126 g/2 = 63 grams.
Oxalic Acid Chemical and Structural Formula
Oxalic Acid Formula is: C2H2O4
Hydrated oxalic acid molar mass is 126 g/mol. Since the chemical formula of this compound can be written as COOH-COOH, it is understandable that oxalic acid is a diacid with the ability to donate two H+ ions. increase. Therefore, the equivalent weight of Oxalic Acid Formula can be calculated using the formula:
Oxalic acid structure – C2H2O4
Preparation of Oxalic acid – C2H2O4
In its anhydrous form, oxalic acid is found to exist in two different polymorphs. Hydrogen bonding occurs in the first polymorph of oxalic acid. This hydrogen bonding creates a chain-like structure at the intermolecular level. The second polymorph of this compound also undergoes hydrogen bonding.
However, in this case, the compound adopts a sheet-like structure at the intermolecular level due to hydrogen bonding. This compound is widely used in esterification reactions due to two important properties. The first property that makes oxalic acid ideal for esterification reactions is its acidic nature. The second most important property of oxalic acid is its hydrophilicity (it tends to seek water).
Properties of Oxalic acid – C2H2O4
Oxalic Acid Formula is an odourless, crystalline, white solid compound. It has a density of 1.9 grams/ml and a melting point of 190 °C. It is commonly available in hydrated form.
It is freely soluble in water, forming a colourless acidic solution. Oxalic anhydride is very hydrophilic and can absorb water. Naturally, it is a strong acid. It is the simplest dicarboxylic acid and reacts like a typical carboxylic acid. As a result, they may form acid chlorides and ester derivatives. It is an excellent reducing agent and an excellent chelating ligand for various metal cations. Students are advised to learn Oxalic Acid Formula from the website of Extramarks.
Uses of Oxalic acid (C2H2O4)
- Used for removing rust
- Applied to make marble sculptures shine
- used in the production of dyes
- used in bleach
- Used to remove food and ink stains
- used for developing photographic film
- Used in wastewater treatment to remove limescale.
The conjugate base of oxalate is the hydrogen oxalate anion, and its conjugate base (commonly known as oxalate) is a competitive inhibitor of the enzyme lactate dehydrogenase (often abbreviated as LDH). LDH catalyzes the conversion of pyruvate to lactate (the end product of fermentation, an anaerobic process) while simultaneously oxidizing the coenzyme NADH to NAD+ and H+. Restoration of NAD+ levels is required for continued anaerobic energy metabolism via glycolysis. Since cancer cells preferentially utilize anaerobic metabolism, LDH inhibition has been shown to inhibit tumour development and growth. This compound, therefore, offers an interesting potential course in the treatment of certain cancers.
Oxalic Acid Formula is a powerful poison. Symptoms of ingestion poisoning include vomiting, diarrhoea, severe gastrointestinal disturbances, kidney damage, shock, convulsions, and coma and death may result from cardiovascular collapse. Oxalic Acid Formula is irritating to the eyes, mucous membranes and skin. Inhalation or ingestion may cause kidney damage and is a powerful poison. Symptoms of poisoning include kidney damage, shock, and convulsions. Toxicity occurs when oxalic acid reacts with the calcium in tissues to form calcium oxalate, disrupting the calcium-to-potassium ratio. Oxalate deposition in the renal tubules can lead to kidney damage. Oxalate poisoning can cause headaches, dizziness, nausea, vomiting, convulsions, coma, and even death and rashes, discomfort, redness, blisters, and slow-healing ulcers can occur with prolonged or repeated exposure. may occur.
Q.1: Determine the molar mass of oxalic acid.
Solution: Its molecular formula is:
atomic weight of C = 12.0107
atomic weight of H = 1.00784
atomic weight of O = 15.999
Its molar mass is therefore:
= 2 x 12.0107 + 2 x 1.00784 + 4 x 15.999
= 90.03 grams per mole.
FAQs (Frequently Asked Questions)
1. Is Oxalic Acid Formula a strong acid?
As an organic acid, it is a weak acid. Oxalic acid is known as a comparatively weak acid. It is weaker than the H3O+ atom. However, it is stronger than acetic acid, benzoic acid, etc.
2. What is the pH of oxalic acid?
The Oxalic Acid Formula constant acid dissociation is 5.4 × 10-2. Oxalic acid is a polybasic acid, so it has two values and has the chemical formula HOOC-COOH.
3. What is the strongest acid in the world?
Carborane superacids can be considered the strongest polar acids in the world because fluoroantimonic acid is a combination of hydrofluoric acid and antimony pentafluoride and the pH of carborane is -18.
4. What is the value of the Oxalic Acid Formula?
The value of the Oxalic Acid Formula lies in the fact that no H+ or OH ions are produced by acids and bases. The acid releases 2 H+ ions, so the valence coefficient for oxalic acid is 2. On the other hand, the number of electrons exchanged with the molecule is called the valence coefficient of that compound for redox reactions.
