Citric acid is a naturally occurring organic acid found in citrus fruits such as lemons, oranges, and limes. It is widely used across various industries due to its excellent chelating properties, acidity regulation, and preservative functions. One of the most commonly used forms of this acid is citric acid monohydrate, which is a crystalline powder with a single water molecule attached. This form enhances its stability and solubility, making it ideal for multiple applications in food, pharmaceuticals, and industrial processes. For high-quality citric acid monohydrate, you can explore options available at Noah Chemicals, a trusted supplier of specialty chemicals.
Chemical Properties and Structure
Citric acid monohydrate is an organic compound with the chemical formula C₆H₈O₇·H₂O. The monohydrate form consists of one molecule of water integrated into its structure, giving it slightly different physical characteristics compared to the anhydrous form. It appears as a white crystalline powder with a slightly tart taste and is highly soluble in water.
Key properties of citric acid monohydrate include:
- Molecular Weight: 210.14 g/mol
- Melting Point: Around 135°C
- pH Level: Typically between 2.2 and 3.0 in a 1% aqueous solution
Its strong acidity and buffering capacity make it valuable in multiple applications where pH control and solubility are crucial.
Uses of Citric Acid Monohydrate in Different Industries
