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 - 7.3). Aqueous solutions of sodium chloride are stable at room temperature.
Aluminum= ≤0.2 µg/g; Magnesium and Alkaline-earth Metals=≤0.01% (as Ca); Arsenic=≤1 µg/g; Iron=≤2 µg/g; Limit of Phosphates =≤0.0025%; Limit of Potassium =≤0.05%.
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.
