Use this class practical to reveal how methanol and ethanol behave differently when treated with iodine and sodium hydroxide solutions. These two important alcohols may be chemically distinguished by using the iodoform reaction. This experiment takes about 20 minutes.
VAPOUR LIQUID EQUILIBRIUM LAB REPORT Page 4 4.0 THEORY Vapor–liquid equilibrium (VLE) is a condition in which a liquid and its vapor (gas phase) are in equilibrium with each other, a condition or state where the rate of evaporation(liquid changing to vapor) equals the rate of condensation (vapor changing to liquid) on a molecular level such ...
In this lab, esterification occurs when an alcohol and a carboxylic acid are reacted in the presence of an acid catalyst, such as concentrated sulfuric acid. Example of an esterification reaction: Other synthetic pathways to esters also exist.
After completing this experiment, the student should be able to: Be able to identify the ester, carboxylic acid, and alcohol functional groups. Be able to systematically name esters. Predict the ester product to be made in each reaction. Use proper laboratory technique for identifying odors.
In this practical, students explore the formation of esters through the ability of different alcohols to react with organic acids. Together, the class can quickly produce a range of esters on a test tube scale, with a variety of interesting smells to sample and compare. As a class experiment this can be organised, if desired, as a class ...
Comparing heat energy from burning alcohols. In this investigation, students use a spirit burner to burn various alcohols while measuring and comparing the amount of heat energy produced. This experiment is suitable for pre-16 students, possibly as an introduction to a topic on fuels.
19 de nov. de 2019 · Ethanol level can be measured by blood, urine, saliva, or breath tests. Toxic concentration is dependent on individual tolerance and usage although levels greater than 300-400 mg/dL can be fatal...
