Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

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‚

Resolution of Matter into Pure Substances – Paper Chromatography Abstract The purpose of this laboratory was to determine how different substances have different solubilities in a given solvent. This was accomplished using the method of chromatography. The solubility of each substance was first determined by dropping a drop or two of each on a line drawn 2 inches above the bottom of a piece of paper. Then the paper was lightly bent in order to tape both sides of the paper leaving about a 4 centimeter

Data Analysis The pH of a liquid affects the brownness of a banana. This experiment was started by the question‚”Does the pH of a liquid affect the browning time of a banana? “ The hypothesis was “that the lower the pH the less brown a banana will turn.”. The experimental group was bananas placed in liquids with varying pH levels : lemon juice‚ lime juice‚ vinegar‚ baking soda water‚ alkaline water‚ and distilled water. This experiment’s dependent variable is the number of spots each banana has
