rainbow-chick said:i'm writing a research paper on the organic medicinal massage oils. i need to know the chemical composition of citric acid and it's pH. can anyone help me?
rainbow-chick said:what i was really looking for was the pH of lemon juice i read somewhere that lemon juice was pure citric acid...?? sounds stupid now that i think about. sorry and thank you for your help!
symbolipoint said:"Pure citric acid" ---- nonsense since citric acid itself is a solid. Lemon juice is a liquid, a solution which contains a few solutes including citric acid. (Condition assumed, room temperature. ) Good thinking on your next thought shown from your message.

Citric acid is a weak organic acid found naturally in citrus fruits such as lemons, limes, and oranges. It is also produced artificially through a fermentation process using certain strains of mold.
The chemical formula for citric acid is C6H8O7. This means that it contains 6 carbon atoms, 8 hydrogen atoms, and 7 oxygen atoms.
Citric acid's chemical composition is determined through various chemical analyses, such as chromatography and spectroscopy. These techniques help identify the specific elements and their ratios present in the compound.
The pH of citric acid is approximately 2.2, making it an acidic substance. This is due to its ability to release hydrogen ions in water, resulting in a low pH value.
Citric acid has a wide range of uses, including as a flavoring agent in food and beverages, a preservative in cosmetics and pharmaceuticals, and a cleaning agent in household products. It is also used in various industrial processes, such as in the production of detergents and as a pH adjuster in water treatment.
