Beschreibung
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 −21°C, depending on the rate of stirring and the size of the ice chunks.
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
- In salt-out procedures in the isolation of DNA
- In high concentrations, for preservation of foods (since bacteria cannot grow in high salt conditions)
