Esterification Lab Introduction Esterification is an important part of organic chemistry that has many practical applications. Esterification can be used to make polymers. In most cases‚ esters are used for scents – they often smell fruity and sweet. In general‚ an esterification reaction results from a condensation reaction between a carboxylic acid and an alcohol. The carboxylic acid group loses an OH group‚ and the alcohol loses and H. For instance‚ the reaction between methanoic acid and methanol

Title: Flame Test Aim: To determine the cation in each of the unknown substance X‚ Y and Z by observing the flame colour of different metal compounds. Introduction: A distinctive feature of many s-block metals is their ability to produce flame colours. At temperature of a Bunsen flame‚ a compound will decompose to give gaseous atoms of its constituent elements. When an electron in the gaseous atom absorbs energy from the flame‚ it will move from an orbital with lower energy to

Personal Care period 4 Michelle Manobanda 2012 The FDA permits the use of mercury compounds in eye makeup at concentrations up to 65 parts per million. The preservative thimerosol‚ found in some mascaras‚ is a mercury-containing product. Mercury is associated with a host of health concerns including allergic reactions‚ skin irritation‚ toxicity‚ neurological damage‚ bioacculumation‚ and environmental damage. Mercury readily passes into the body through the skin‚ so normal use of the product

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to
