- A 10.00 mL sample of ethanol is added to 250.0 mL of water in order to observe the freezing point depression of the water. Consider the possible errors in this experiment, and determine whether each would cause the freezing point of the water to increase, decrease, or remain the same compared with the expected results. It is discovered that the 10.00 g ethanol sample is actually 95% ethanol and 5% water. The ethanol sample is left out for several minutes before being added to the water, allowing a significant amount to evaporate. Instead of starting the experiment with room temperature water, the experiment is started with cold water. Some of the water is splashed out of the container before the ethanol is added. Some of the ethanol and water solution is spilled out of the container during temperature measurement.arrow_forwardSuppose that a solution made from an unknown solute dissolved in solvent X.
