CH3COONa3H2O

CH3COONa3H2O, also known as sodium acetate trihydrate, is a chemical compound with the formula C2H3NaO2·3H2O. It is a white, crystalline solid that is commonly used in various industrial and laboratory applications. The compound consists of sodium acetate (CH3COONa) and three molecules of water (H2O). Sodium acetate is a salt derived from acetic acid and sodium hydroxide, and it is widely used as a buffering agent, pH adjuster, and preservative in food, pharmaceuticals, and cosmetics. The addition of water molecules to form the trihydrate enhances its solubility and stability, making it more suitable for certain applications. CH3COONa3H2O is typically prepared by reacting acetic acid with sodium carbonate or sodium bicarbonate, followed by crystallization to obtain the hydrated form. It is non-toxic and has a mild, vinegar-like odor. The compound is also used in the synthesis of other chemicals and as a component in some cleaning products.
