Which procedure can be used to determine the melting point of ice?

A. Mix ice with water and immediately measure the temperature
B. Place a beaker of liquid water in the freezer and measure the temperature after the water has become solid
C. Warm a beaker of ice on a hot plate until on the liquid remains and measure the temperature of the liquid
D. Add ice to liquid water one at a time and measure the temperature of the water once added ice cubes no longer melt

To accurately determine the melting point of ice, the correct procedure is:

A. Mix ice with water and immediately measure the temperature.

This method allows you to create an equilibrium between ice and liquid water. When ice is mixed with water, the temperature will stabilize at the melting point of ice (0°C at standard atmospheric pressure) as long as ice is present. Option B would not reliably indicate the melting point because it involves changing the state of water into ice; option C is incorrect because it suggests raising the temperature beyond the melting point; and option D involves measuring the temperature at the point of ice addition, which may not reflect the melting point accurately.
