What is oxalic acid used for?

The only domestic use I have heard of for oxalic acid is to remove iron stains. In the laboratory it is used in the preparation of carbon monoxide gas by heating the crystals with concentrated sulphuric acid and in volumetric titrations against alkalis as oxalic acid is a stable solid making it easier to make accurate solutions.

This depends on why sulfuric acid is "king".  In industry, sulfuric acid is the most used chemical by weight (other than water).  The opposite, "the serf" or "fool" would be a chemical rarely used.  The choices are too numerous to list.

carboxylic acid, as represented by -(C=O)-OH. For more info, check the source.

It's an iron bearing oxide compound used as an abrasive.\n\nIt's only one of the abrasives in Emery Cloth.\n\nIt's also used as a powder in comercial applications, or in a colodial suspension for lapping compounds..

Vinegar.  Pickles and such help, but drinking a small amount of vinegar is gross yes but works the best.

from the link below, which includes a lot more information:\n\nCyanic acid (also called fulminic acid) is an unstable (explosive), poisonous, volatile, clear liquid with the structure of H-O-C=N (the oxoacid formed from the pseudohalogen cyanide), which readily polymerizes to cyamelide and fulminic acid. Cyanuric acid (also called pyrolithic acid), white monoclinic crystal with the structure of [HOC(NCOH)2N], is the compound of polymerized cyanic acid. Cyanic acid hydrolyses to ammonia and carbon dioxide in water. Its salts and esters are cyanates (or called fulminates). Esters of normal cyanic acid are not known. There is another isomeric cyanic acid with the structure of H-N=C=O, which is called isocyanic acid. Its salts and esters are isocyanates. Cyanates (or Isocyanates) are used in the manufacturing pharmaceuticals, pesticides, textile softener, lubricants and industrial disinfectants through the conversion to polycyclic compounds (such as hydantoins and imidazolons) They are used as plastic additives and as heat treatment salt formulations for metals. Thiocyanate is a salt or ester of thiocyanic acid (HSCN). Aqueous solutions of thiocyanic acid , also called sulfocyanic acid, are very strong acids of the  equilibrium mixture of thiocyanic and isothiocyanic. Thiocyanates are bonded through the sulfur(s) with the structure R-S-C¡ÕN or the isomeric R-N=C=S (isothiocyanates). Thiocyanates are bonded through the sulfur(s) which replace for the oxygen (O) atom. Thiocyanates are the sulfur analog of isocyanates. Organic as well as metallic thiocyanates [CuSCN, Ca(SCN)2, NaSCN, KSCN] are very versatile compounds. They have wide range of applications including manufacturing industrial chemicals, pharmaceuticals and pesticides. It is used in freezing solutions, fabric dyeing, electroplating, steel pickling, printing, and corrosion inhibitor against acid gases. It is used in photography industry as a stabilizer or accelerator.

It is a strong oxidizer therefore used in sterilization or as a disinfectant. Its chemical formula is also known as peracetic acid C2H4O3.

Its hydrochloric acid. There is an ion complex formation in its solution in water. It doesnt occur in carbonic acid though it has got more dry ions in paper. By the way, what is sodium hydroxate? You meant ide?

CO2 +H2O<-->H2CO2<---->HCO2 + H\nCarbonic Acid can react with Hidrogen ions (which lower the pH of the blood) to form bicarbonate; which can be later removed by the system in the kidneys or through respiration.  The formation of bicarbonate removes an H ion from solution thus helping mantain pH equillibrium in the body at around 7.4

Muriatic acid.  It is still sold under this name in hardware store and building material outlets.

The best use of HCl is for washing / cleaning the toilet bowels and ceramic tiles. It can effectively remove white scales usually deposited on the faucets , showers etc. (Use 5 times diluted for this purpose). DO NOT USE ON NATURAL MARBLE. It will instantly dissolve the upper surface of the marble tiles.\nIt only is a hard stain / debri removal agent NOT a disinfectant.\nBE VERY CAREFUL while using the acid as it can cause severe burns on skin and irreversible damage to eyes if in contact.

I don't know where you live but there is a product called 'oxi action' that is sold under different brands. Try it and good luck!

Look at your diagram of Kreb's Carboxylic Acid Cycle.\nPick out oxaloacetic acid.\nWhat does it do?\nWhere does it come from? Remember the process is a cycle.
