A calorimeter and a thermometer.
Salt lowers the melting point of ice.
The melting point of salt (Sodium Chloride) is 801 °C
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
The melting point of ice decreases when salt is added.
Adding salt to melting ice lowers the freezing point of water, causing the ice to melt at a lower temperature. This results in faster melting of the ice.
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.
To control variables when determining the melting point of salt water, you should keep the concentration of salt consistent, use the same type of salt, ensure the pressure remains constant, and keep the volume of water consistent. Controlling these variables will help ensure that any observed changes in the melting point are due to the salt concentration rather than other factors.
When salt is added to ice, the melting point goes up, causing the ice to melt faster. That's why is cities where ice frequently is one sidewalks in winter, people shovel salt onto the sidewalk.
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
The melting point of sodium chloride is 801 0C.
