740 Words3 Pages

Nora Azmani IB3G Chemistry HL Dr. Petersen Date of submission: 01/12/2014 Comparing the Enthalpy Changes of Combustion of Ethanol (CH3CH2OH) and Butanol(CH3CH2CH2CH2OH) in order to determine which one of them that is the more efficient as a fuel. Objective The purpose of this lab is to determine the fuel efficiency of the two alcohols Ethanol and Butanol, by comparing their respective enthalpy changes. The most efficient fuel will be the one with the highest enthalpy change of combustion. The enthalpy changes will be determined by examining the effect the alcohols have on the water’s temperature change. Balanced Equations for the Combustion reactions of Ethanol and Butanol: Ethanol combustion: CH3CH2OH(l)+ 3O2 (g) --> 2 CO2 (g) + 3 …show more content…

Measure and record the total mass of water and the beaker. Subtract this with the value from step 2 in order to achieve the initial mass of water. Using the electronic scale, Measure and record the mass(g) of the alcohol burner, continue by measuring 150 g of ethanol and insert it into the alcohol burner. Place the wire gauze on top of ring clamp belonging to the ring stand. Place the 250ml beaker on top of the wire gauze. Arrange so that there will be a 10 cm distance between the wire gauze and the wick of the burner when the alcohol burner is placed underneath the clamp. Use a thermometer to measure and record the initial temperature of the water. Light the wick of the alcohol burner containing ethanol using a lighter or a match. Use a stopwatch to track the time of the combustion of ethanol. While the water within the beaker is being heated, use a stirring rod to stir it. Put the fire out when 4 minutes have elapsed. For safety precautions, let it cool off a bit before using the scale to measure and record, the final mass of the alcohol burner containing the ethanol. Subtract the mass of the alcohol burner gained in step 4 to achieve the final mass of the alcohol. Use the thermometer to record the final temperature of the distilled

    The temperature probe was then quickly cooled to room temperature. When this was achieved, the hot water was immediately transferred into the calorimeter. This method of keeping the temperature probe cooled before measuring a new temperature was repeated throughout the entire experiment. Temperature data was collected for 180 s while swirling the temperature inside the calorimeter. The calorimeter still contained the warm water.

    Using the thermometer, the temperature was measured and recorded. Then, the 25-mL graduated cylinder was filled with 25 mL of distilled water, and its mass was measured and recorded. The density of the water was found using the temperature and the Density of water index. Moreover, the calculated volume of water was calculated using the formula of density, and the difference between observed volume and calculated volume was found. This process was then repeated using the 50-mL beaker and the results were recorded.

    In relation to a previous experiment in which the students determined the boiling points of two liquids, it was deduced that the boiling point of [propyl and methyl] alcohol was estimated to be around 80oC. According to numerous sources, ethanol boils (and consequently evaporates) at around 78.5oC[7] a much lower temperature compared to the alcoholic beverage’s other ingredients—water, for example, boils at precisely 100oC. It is immensely possible that because of this, ethanol is isolated from the beverage sooner than said beverage’s other components. Perhaps, if the students worked within
