The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ can be the same or different; at equilibrium‚ the concentrations of both reactants and products are constant. In this experiment set up‚ the reaction between ethanoic acid and ethanol to produce ethyl ethanoate and water is a reversible reaction as shown by the following equation: CH₃COOH + CH₃CH₂OH↔CH₃COOCH₂CH₃ +H₂O The Equilibrium Law states that at equilibrium the ratio [CH₃COOCH₂CH₃][H₂O]/[CH₃COOH][CH₃CH₂OH] is constant

VODKA MAKING PROCESS AND DISTILLING PROCESS Vodka is defined in the United States Standards of Identity as “neutral spirits so distilled‚ or so treated after distillation with charcoal or other materials‚ as to be without distinctive character‚ aroma‚ taste‚ or color.” As Vodka is a neutral spirit‚ it means that it can be obtained by the distillation of any product with fermentable carbohydrates on it‚ like grains (rye‚ corn or wheat) or products like potatoes‚ beets or sugar beets; even grapes

Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide and ethanol. They are found in various places‚ which include: in soil‚ on plants‚ in salt water‚ and even along a digestive tract. Yeast‚ depending on the type‚ can reproduce asexually‚ by budding (and are usually attached and stay that way most of their lives)

Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first piece
