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: Preparation and isolation of an Ester Aim: To make an ester and purify it Background Theory: Esters are derived from carboxylic acids and alcohols with the presence of a catalyst. A carboxylic acid contains the -COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. Sulfuric acid (H2SO4)is used as a catalyst for this reaction in order to accelerate the rate at which the product is formed. The general formula of an ester is RCOOR’ in

Distinction – Analyse the benefits of understanding diversity. When we truly understand and value diversity and correctly apply the care values‚ there are many additional benefits such as; empowerment‚ independence‚ inclusion‚ equality‚ respect‚ dignity‚ opportunity‚ access‚ participation and anti-discrimination practise. I am going to explain why these benefit service users and how they feel when they are treated like this in the form of a case study when I visited St. Peters Court. CASE STUDY
