Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography
Aim: To analyze a mixture of alkenes by gas chromatography.
Introduction: In this lab, we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids, alcohols protonate to f...
Gas Chromatography: Purifying alcohol
The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol...

Chromatography is a very important analytical tool because it allows the chemist to separate components in a mixture for subsequent use or quantification. Most samples that chemists want to analyze are mixtures. If the method of quantification is selective for a given component in th...
How can you tell pigment separation by using Chromatography?
To prepare a chromatogram, separate pigments in a leaf and interpret the chromatogram.
If I am to put a chromatography paper into a solvent, then it would separate the pigments depending on their Rf va...
How Far Can Spinach Go?
the process of photosynthesis is the process that plants and some bacteria get there energy from sunlight and change it to sugar. We can summarize this whole process into this equation: 6H2O + 6CO2 ----------> C6H12O6+ 6O2 which is read as six molecules of water plus six...
Ideal Gas Law Lab
1. Procedure: First, we used a balance to weigh the canister of gas, and recorded that mass as the original weight.
Then, we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water i...
