Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample

Eco-Column Lab Write up Alicia Whiteley Block 4 Abstract: In this research and experiment we were testing whether or not we can maintain a healthy eco-system based off creating one from scratch. We initially went into this experiment confident that we were going to be able to keep our fish alive which was proven wrong mid-way through due to high levels of turbidity and the state of the fish. After collecting all of our data‚ we maintained a healthy terrestrial level and a good PH

1 INTRODUCTION BACKGROUND OF THE STUDY All spines have curves. Some curvature in the neck‚ upper trunk and lower trunk is normal. Humans need these spinal curves to help the upper body maintain proper balance and alignment over the pelvis. However‚ when there are abnormal side-to-side (lateral) curves in the spinal column‚ we refer to this as scoliosis. Scoliosis occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such

Introduction Flash-Column Chromatography is another useful technique used to separate and purify complex mixtures of compounds. In this experiment‚ TLC is used to determine the best solvent system for the column. Due to Flash-Column Chromatography1 being an inexpensive technique‚ many scientist use this process for drug and natural product purification. Method By using the information from Experiment 6B‚ the TLC solvent system used was 30% EtOAc: 70% Hex. Experiment 7 was broken into two parts‚
