), which transfers heat between the bath and the vessel; (3) an additive to depress the melting point of the solid/liquid system.
Mixing solvents creates cooling baths with variable freezing points.
Relative to traditional cooling baths, solvent mixtures are adaptable for a wide temperature range.
However, adding a salt such as sodium chloride will lower the temperature through the property of freezing-point depression.
The American Chemical Society notes[citation needed] that the ideal organic solvents to use in a cooling bath have the following characteristics: In some cases, a simple substitution can give nearly identical results while lowering risks.
