Title and Abstract

The Effect of the Concentration of Salt on The Melting Point of Ice

Our aim is to investigate the effect of salt concentration on melting point of ice, to also find out about the ‘Freezing Point Depression’ that is related to the effect of salt concentration on melting point of ice.

Thus, this research is essential because as salt decreases ice’s melting point, it may make the lives of people who live in cold places easier. An example of this is that salt was used on icy sidewalks in cold countries to melt the icy sidewalks faster, causing the path to be less slippery.

    To solve this investigation, we would freeze saltwater into ice and measure the flow of their temperature over the length of 3 hours, by using a temperature probe and a data logger, and the results will be recorded in graphs, and we can find out the melting point by referring to the length of temperature where it is particularly consistent.

    The results we gathered is that generally, the higher the salt concentration, the lower the melting point of ice is. This excludes the parts where the ices with the salinities of 0.2 and 0.25 respectively have the same melting point, and that the ice with no salinity has a “lower melting point” than the ice with the salinity of 0.05.
