What is the chemical equation[composition] of citric acid ?
2-hydroxypropane-1,2,3-tricarboxylic acid C(C(=O)O)C(CC(=O)O)(C(=O)O)O C6H8O7 http://en.wikipedia.org/wiki/Citric_acid http://pubchem.ncbi.nlm.nih.gov/summary/… Note: It can exist in different forms as well (see the following links) hydrate (C6H10O8) 2-hydroxypropane-1,2,3-tricarboxylic acid hydrate http://pubchem.ncbi.nlm.nih.gov/summary/… anion (C6H5O7-3) 2-hydroxypropane-1,2,3-tricarboxylate http://pubchem.ncbi.nlm.nih.gov/summary/… oxaloacetic acid (C4H4O5) 2-oxobutanedioic acid http://pubchem.ncbi.nlm.nih.gov/summary/… Sorry, the IUPAC names aren’t showing up
C6H8O7 Is a common chemcial equation, 2-hydroxypropane-1,2,3-tricarboxylic acid Is the chemical name, Citric acid is a weak organic acid found in citrus fruits. It is a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of almost all living things. It also serves as an environmentally benign cleaning agent and acts as an antioxidant. Citric acid exists in a variety of fruits and vegetables, but it is most concentrated in lemons and limes, where it can comprise as much as 8% of the dry weight of the fruit. Properties The physical properties of citric acid are summarized in the table at right. The acidity of citric acid results from the three carboxyl groups COOH each of which can lose a proton in solution. If this happens, the resulting ion is the citrate ion. Citrates make excellent buffers for controlling the pH of acidic soluti
