Sodium chloride 99.0-100.5%, powder USP
Sodium chloride

Soluble in water (357 mg/ml at 25 °C; 384 mg/ml at 100 °C), glycerol (100 mg/ml); very slightly soluble in ethanol. Solubility in water is decreased by HCl; almost insoluble in concentrated HCl. Aqueous solutions are at a neutral pH (6,7 to 7,3). Aqueous solutions of sodium chloride are stable at room temperature.


Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0,9% w/v in water), density gradients, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA. It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. A salt-ice mixture in the ratio of approximately 33 g sodium chloride to 100 g ice (at -1 °C) will drop in temperature to as low as -21 °C, depending on the rate of stirring and the size of the ice chunks.
