Purpose: To separate food colorings into their component dyes using paper chromatography.
Materials: Chromatography paper, Food coloring, Ruler, Pencil, Solvent solution, Test tubes, Test tube rack.
Safety precaution: wear aprons, to make sure that you don’t get any of the
Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a sol
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
The Empirical Formula of a Copper Oxide
To convert an unknown copper oxide to copper (Cu) metal using natural gas to provide a reducing environment as shown below:
Cu O (s) + CH (g) ¨ Cu (s) + Co (g) + H O (g)
From the mass difference between
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
Unknown Lab Report
