how oxalic acid is made?
308615
Oxalic acid is more correctly known as ethanedioic acid and has the formula H2C2O4. It is made commercially by treating sugar with nitric acid or cellulose with sodium hydroxide. The acid is very soluble in water - a litre will dissolve 150g - and it forms a corrosive solution.

The initiating step of the citric acid cycle occurs when a four carbon compound (oxaloacetic acid) condenses with acetyl CoA (2 carbons) to form citric acid (6 carbons). The whole purpose of a "turn" of the citric acid cycle is to produce two carbon dioxide molecules.

Nutritional powerhouses like kale, collards, spinach, chard, and beet greens all contain oxalic acid. Oxalic acid occurs naturally in many fruits and vegetables, but when it comes to leafy greens, it's present in higher concentrations.

Production of Citric Acid It is an organic carboxylic acid and can be extracted from the juice of citrus fruits by adding calcium oxide to form calcium citrate, which is an insoluble precipitate that can be collected by filtration; the citric acid can be recovered from its calcium salt by adding sulfuric acid.

Some of the basic ingredients to make these foods are very high. White flour and brown rice flour are high in oxalate so everything you make from them will be high.

HClO4 (perchloric acid) is a stronger acid than HClO3 (chloric acid). ... Both HClO4 and HClO3 are oxyacids of chlorine, and the oxidation number of chlorine in them are +7 and +5 respectively. Higher the oxidation number stronger will be the acid, for the oxyacids of a particular element.

Oxalic acid's main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent), Bar Keepers Friend is an example of a household cleaner containing oxalic acid.

Oxalic acid occurs in lots of foods in small amounts, and a few foods in large amounts. Swiss chard has most (700mg per 100g), but spinach (600mg), rhubarb (500mg), cocoa (500mg), beetroot (300mg) and peanuts (150mg) also have a lot.

Hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon dioxide and water.

Oxalates impair the absorption of nonheme iron. Oxalates are compounds derived from oxalic acid and found in foods such as spinach, kale, beets, nuts, chocolate, tea, wheat bran, rhubarb, strawberries and herbs such as oregano, basil, and parsley.

Methanoic acid, better known as formic acid [64- 18-6], HCOOH, Mr 46.03, is a colorless, corro- sive liquid with a pungent odor. It is completely miscible with water and many polar solvents but only partially miscible with hydrocarbons. Formic acid derives its name from ants (lat.

Manufacture. Sulfuric acid is produced from sulfur, oxygen and water via the contact process. In the first step, sulfur is burned to produce sulfur dioxide. This is then oxidised to sulfur trioxide using oxygen in the presence of a vanadium(V) oxide catalyst.

Baking soda can be produced by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide, or by treating a sodium carbonate solution with carbon dioxide. It can also be prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water.

Patxaran is made by soaking sloe fruits, collected from the blackthorn shrub, along with a few coffee beans and a cinnamon pod in anisette, for one to eight months. The process produces a light sweet reddish-brown liquid around 25-30% in alcohol content by volume.

Figure 1 Formic acid (methanoic acid, HCOOH) is a weak acid that occurs naturally in bee and ant stings. Formic acid makes up 55–60% of the body mass of a typical ant; its name comes from 'formica', the Latin word for ant.

Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or to fatty acids through acetyl-CoA. It can also be used to construct the amino acid alanine, and it can be converted into ethanol.
