This scientific experiment will entail the rate at which ice will melt with different types of salts that include, table salt, sea salt, and rock salt. Salt melts ice essentially because adding salt lowers the freezing point of water. Although we know that salt has the ability to melt ice, we are testing whether sea salt, table salt, or rock salt melts ice more efficiently by calculating the amount of time it takes to melt the ice. We will begin by placing the same quantity of each type of salt onto the same amount of ice. We will time the rate at which the ice melts, and at a certain point, based on the percentages of how much the ice has melted, we will determine the most efficient salt for melting ice. Table salt has all of its minerals removed, which could possibly affect the rate at which table salt melts ice. On the contrary to rock salt, both sea salt and table salt are finer, causing different effects in melting ice. Due to the different particle sizes of these different salts, the results on melting the ice may vary. When adding these different types of salt to ice, the water molecules of ice are replaced by the salt molecules. The rate of freezing decreases because of the added molecules, which therefore lead the ice to melting. Rock salt comes in larger particles than do table salt or sea salt. This is in part to why we believe that rock salt will melt through the ice more efficiently due its larger composition of its particles, leaving residue behind and…
