To detemine the heat of combustion of ethanol and methanol. Procedures and conclusion.

EXPERIMENT AIM: To determine the experimental heat of fire of m fermentation alcohol (CH3OH) and ethanol (CH3CH2OH). To decide which would be a better choice to stupefy on a camping trip. MATERIALS: 1 Copper container 1 Clamp 1 Spirit Lamp with Wick neutral spirits 1 reelect Stand Methanol 1 Box of Matches Water 1 electronic Balance Thermometer PROCEDURE: Firstly, footfall the weight of the desert Copper container on the electronic balance. Record your results in a table. Secondly, fill the bull container with 100ml of water. Thirdly, Attach the copper container to the clamp which is them tie to the retort stand. Fourthly, beak the weight of the spirit burner containing known total of Methanol (CH3OH). Fifthly, Measure the initial temperature of the water with the thermometer. Then swingy the spirit lamps candle and place it under the copper container. Sixthly, plump up the water use the thermometer and constantly check the temperature. Once the temperature is 10oC great than the initial temperature, express the spirit burner. Seventhly, reweigh the mass of the spirit burner. Eighthly, recapitulate steps 1 with to 7 for ethanol (CH3CH2OH).

The combustion of Methanol and Ethanol can be represented through and through: Methanol: 2CH3OH(l) + 3O2(g) 2CO2(g) + 4H2O(l) 2(358+463+(414x3)) + (498x3) (804x2x2) + (463x2x4) 5620 6920 6920-5620= 1300 1300/2= -650 KJ/mole Ethanol: CH3CH2OH(l) + 3O2(g) 3H2O(l) + 2CO2(g) 346+358+463+ (414x5) + (498x3) (804x2x2) + (463x2x3) 4731 5994 5994-4731= -126 3 KJ/mole mention: combustion values are n! ot exact to the apply ascribable to different values of bond energies. Risk sagaciousness Methanol: inhalant and ingestion whitethorn be fatal. Inhalation also starts low blood pressure, headache, nausea, vomiting, dizziness, narcosis, aboriginal nervous establishment depression and suffocation. May irritate beat and eyes and temporarily damage corneas. inhalation may cause blindness, vomiting, headaches and dizziness. Ethanol: Ingestion may be fatal. May be mantled through the skin.
