Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different...

Questions A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason? Water will boil at lower temperature at sea level. If the water did not boil at 100c the reason would probably be that you are above sea level. B. While heating two different...

Separation Techniques

Separation techniques are an important part of chemistry. However, their importance is not just limited to chemistry; they are also used in our daily lives. Separation techniques are methods used to separate and/or purify mixtures. There are many kinds of separation techniques that are used in our day to day life, such as filtration, Centrifuging, Decanting, fractional distillation and sieving. Each of these methods has their own specific uses in our daily lives which make our chores much easier...

Separation Techniques

Main Separation Techniques A mixture is usually an impure substance and it is necessary to separate mixtures in order to obtain its pure components. The components of a mixture are not chemically combined. Therefore, they can be separated by physical methods; the components of a mixture will still contain their properties. Methods used to separate mixtures depend on the physical differences between the components of the mixture. The main separation techniques include: Filtration A method which...

during the experiment. Phthalic Acid melted just 20°C less than the standard melting point for Phthalic Acid. Naphthalene melted 10°C less and Benzoic Acid also did not reach the standard melting point. Reasons for a low percent Recovery for Phthalic Acid and Naphthalene is probably because not all of the solid were collected when filtered out. Reasons for Benzoic Acid being over 100 % is probably because there was an excess of solute and it was not filtered out correctly. Conclusion To conclude...
