Organic Chemistry Laboratory Report. Experiment 1: Crystallization. Objectives: 1. To study the crystallization process. 2. To identify the best suitable solvent to use for the crystallization process. 3. Gain an experience in purifying an organic compound by the techniques of the crystallization. Introduction. Crystallization is a technique which chemists use to purify solid compounds. It is one of the fundamental procedures each chemist

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

person being infected with Leptospirosis might lessen. The benefits of an organic fertilizer compared to a chemically made fertilizer are that the plants were able to grow taller‚ faster‚ healthier‚ and were able to bear more fruits. Our project will test if every day produce‚ such as the yogurt can be mixed with animal feces just like how egg shells and banana peels are used to decompose waste and create a rich‚ organic fertilizer. Our project will benefit not only the environment of Guam‚ but

The debate between organic and processed foods has been an extremely controversial topic over the past few decades. Food in general is a key source for all humans and is an everyday necessity. Food gives us nutrition and energy to live throughout our life. Moreover‚ the development of making foods has evolved and has changed from organic to processed foods in recent years. Organic foods are grown naturally with no type of preservatives‚ pesticides‚ and hormones “Organic Foods: What You Need to Know

is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains a watersoluble red pigment‚ betacyanin

Comparison between Organic and Inorganic Compounds Organic Compounds | Inorganic Compounds | *Organic Compounds are composed of few elements only.C‚ H‚O‚N‚S‚P and halogens are the most common. | * Inorganic Compounds are composed of all the known elements. | *They are generally found in living matter‚ i.e.‚ animals and plants. | *They are generally obtained from non-living matter‚ i.e.‚ minerals. | *They are usually gases‚ liquids or solids having low melting points. | *They are usually solids

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the
