The effect of sodium chloride temperature on ice - Essay ExampleThese bonds hold the molecules together forming the unfluctuating ice (Churchill et al). The salt ions dissolved alter the existing hydrogen bonding in the solid ice and this has an effect on the normal freezing layer of the ice causing the temperatures to drop. In this experiment we are going to determine the effect of salt on the temperature of ice.In the first bowl, when the salt is added on the ice, at first nothing happens but after sometime, the temperature of the ice drops before the ice starts melting. The ice the melts step by step and the temperature increases. In the second bowl, the ice starts melting at 0oC a.nd melts gradually as temperatures increases.When salt is added to ice, it is able to lower the freezing point of any water molecules that are on the surface of the ice and this prevents it from freezing again accordingly helping to melt the ice surrounding the solid ice. Water that is pure in natur e has its freezing point fixed at 0oC while salt is able to melt down ice to a temperature of about
