Computer The. Analysis of Alum 158 After a compound has been synthesized‚ tests should be carried out to verify that the compound fonned is indeed the compound desired. There are a number of tests that can be perfonned to verify that the compound is the one desired. In Experiment 15A‚ you prepared alum crystals‚ KAl(S04)z·12H 20. In Experiment 15B‚ you will conduct a series of tests to detennine if your crystals are really alum. The first test is to find the melting temperature of the

After 14 years of trial and error‚ he developed a process he called Appertizing. Fruits‚ vegetables‚ fish‚ or meat was sealed in stoppered bottles and the filled bottles were immersed in boiling water; the heat sterilized the bottles and food alike. Appert knew nothing of enzymes or bacteria‚ nor did anyone else in his day. He did observe that when food was heated in the sealed bottles‚ the food remained good as long as the seal was not broken. The food remained edible until the bottles were

Thermochemical Biomass Gasification – A Review of Technologies Abstract Gasification (in the context of this paper) is an energy process that produces a gas which can be used to substitute fossil fuels. It is a process which enhances biomass’ usefulness as a renewable resource as the product gas (syngas) can easily be transported along existing gas pipelines‚ and can either be mixed with‚ or used as a replacement for natural gas combustion in gas turbines for power and heat generation. Syngas

Mabel M. Kimble September 21‚ 2014 Chemistry 234 Recrystallization of Benzoic Acid ABSTRACT The recrystallization of Benzoic Acid was performed to fully master the ability to purify a solid compound. This form of purification technique is especially important in chemical identification‚ where the melting point of the compound is taken to confirm its purity. In order to perform recrystallization a solubility test much be completed. Four solvents (95% Ethanol‚ Petroleum Ether‚ Acetone and distilled
