Dry ice boiling point celsius
A bath of ice and water will maintain a temperature 0 °C, since the melting point of water is 0 °C. However, adding a salt such as sodium chloride will lower the temperature through the property of freezing-point depression. Although the exact temperature can be hard to control, the weight ratio of salt to ice influences the temperature: • −10 °C can be achieved with a 1:2.5 mass ratio of calcium chloride hemihydrate to ice.
