results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant light source. This would have aided in the plant growing faster than other forms of plant species. When experimenting with the spinach plant blue light worked exceedingly well in making the plant grow faster with there being a decent

separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at different rates. Hypothesis: If chlorophyll is removed from the plant‚ then the different pigments in the plant can be visible. Materials: -Spinach -Coin -Chromatography paper -Ruler

Mr. Sousa Organic Chemistry ACL 8 January 2015 Chromatography Chromatography is a physical method of separating substances based on their properties‚ by distributing their components between a mobile and stationary phase. Chromatography is useful for observing mixtures and solvents‚ since it can be used to determine the relative bond strength of various compounds‚ a substances phase‚ and it can also the identity of unknown substances. Chromatography allows for the separation of chemical mixtures

Solubility as a Property of Matter A Lab of Chemicals‚ Chromatography‚ and Crime! Chemistry is a natural science that deals with the composition of matter and the changes it undergoes. At crime scenes‚ investigators often find unknown materials that need to be identified. If an unknown material is a mixture‚ an investigator may want to know one or two things about it: What are the ingredients of the mixture? Is the mixture found at the scene the same as a known mixture? A mixture is a collection

Paper chromatography is one of the easiest methods of chromatography. It is a method of planar chromatography (stationary phase is in form of a plane). Paper chromatography follows the basic principle of chromatography‚ which states that substances or components are distributed in between the stationary phase and the mobile phase. It is an analytical technique‚ where only a small amount of a sample is used for separating and identifying its components. Like any other method of chromatography‚ paper

Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography‚ a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action‚ the. components

Determining Red 40 Concentrations Using Absorption with Beer’s Law Introduction I like color and enjoyed learning about wavelengths and the spectrum of light‚ so I considered incorporating something related to that into my Internal Assessment. We also had just used concentrations in our Group 4 Project‚ so when I found an experiment that dealt with both of these I thought it was a great idea. This experiment is not completely original; the basic concept has been used multiple times. It uses Beer’s

Biology Lab report #1 The uptake of neutral red dye in a yeast cell using different solutions Abstract Every cell transports materials in and out throught something called a membrane. There are many different methods of transport in the cell Saccharomyces cerevisiae (Serrano‚ 1977) We want to know does adding higher concentrations of azide more effectively block dye transport? We tested the transport of dye in yeast cells with a metabolic inhibitor. When we did this we showed no difference

Separation of Amino Acids by Cation Exchange Chromatography Introduction and Purpose: Amino acids are small biomolecules that have a carboxylic acid backbone in common‚ as well as an amino group attached to a saturated carbon. There are many amino acids‚ but there are 20 most commonly know amino acids. Amino acids are the fundamenta building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment
