Use a thermometer to record the final temperature of the saturated solution and record in the data table below. Formulate a hypothesis of what you think will happen in this experiment. Subtract the final mass of the weighing boat and salt from the initial mass of the weighing boat and salt for the tap water and record in the table below. This is the amount of salt that dissolved in the tap water. Repeat step 1 for the cold water trial and the hot water trial and record in the table below.
