    used to purify solid organic compounds. Using the recrystallization technique‚ a solid compound is dissolved in a solvent and the compound slowly crystallizes as the solution cools. Using a filtration technique‚ a pure solid is produced when the molecules of the impure particles in the compound are excluded from the crystal lattice. After obtaining the pure compound‚ a melting point determination procedure can be done using a mel-temp device to correctly identify the compound if its identity is

    altering carbohydrates into lactic acid (Helmenstine‚ 2013). Fermentation can be used in the food and drink industry as well‚ examples of this is bread. In the process of fermentation with bread‚ yeast produces carbon dioxide‚ alcohol and other compounds which enable the dough to rise and modify its physical properties. Louis Pasteur stated that “ All yeast which ferment bread‚ beer‚ wine and cider corresponds to microscopic living cells of a microscopic fungus Saccharomyces cerevisiae . Many varieties

    Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a & b) are

    The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water)‚ by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity
