Sodium chloride ≥99.0%, white crystalline powder ACS
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 has a neutral pH (6.7 - 7.3).

Bromide= ≤0.01%; Magnesium (Mg)= ≤0.001%; Sulfate (SO4)= ≤0.004%; Iron (Fe)= ≤0.0002%; Calcium (Ca)= ≤0.002%; Chlorates and Nitrates (as NO3)= ≤0.003%; Nitrogen Compound (as N)= ≤0.001%; Phosphate (PO4) 0.0005%; Potassium (K)= ≤0.005%; Iodide (I)= ≤0.002%

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.
