Description
Sodium chloride is used in a wide variety of biochemical applications, including:
- Intravenous fluids (normal saline is 0.9% w/v in water10)
- Density gradients
- A diluent to increase ionic strength in buffers or culture media
- In salt-out procedures in the isolation of DNA
- In high concentrations for preservation of foods, since bacteria cannot grow in high salt conditions
A salt-ice mixture in the ratio of approximately 33g sodium chloride to 100g ice (at −1°C) will drop in temperature to as low as &minus’21°C, depending on the rate of stirring and the size of the ice chunks. Excess amounts of sodium chloride can destroy electrolyte balance and cause death in most animals, including humans.
