Temperatures of Ice-Water Mixtures

Procedure Measure the temperature of ice that has been freshly removed from the refrigerator. Heat the ice using a burner while constantly stirring using a thermometer. Measure the temperature regularly at certain intervals. Intermittently, add different portions of ice or water to this mixture, stir and measure the temperature when it stays constant. 

Observation The ice that has just been taken from the ice compartment has temperatures under 0°C. All other ice-water mixtures show a temperature of 0°C. 

Tip The fact that all ice and water mixtures - independently of the mass of ice and water - show a temperature of 0°C, can lead to the concept of chemical, dynamic equilibrium of forward and backward reaction (see Chap. 6).
