April 04‚ 2014 Fisher Esterification Introduction: Esters are one of the most common derivatives of carboxylic acids and are widely distributed in both nature and industry. A Fischer Esterification is the formation of an ester and water from alcohol and an acid. It is the simplest means of synthesizing an ester and requires the reaction of a carboxylic acid and an alcohol. The general reaction of Fischer esterification is‚ CH3CO2H + ROH ↔ CH3CO2R + H2O (reaction1) CH3COOH + ROH ↔

Agar is also used in medicines to promote peristalsis and relieve constipation and is resistant to a breakdown by bacterial enzymes. Sodium carbonate‚ Na2CO3‚ also known as washing soda or soda ash‚ is a sodium salt of carbonic acid. It can be extracted from the ashes of many plants and has a cooling alkaline taste. It is one of the most basic industrial chemicals. The acid’s Ph scale is always lower than

Research The Chemical name for Baking Soda: Baking soda is sodium bicarbonate. The molecular formula of sodium bicarbonate is NaHCO3. What Baking Powder contains: Baking powder is a raising agent that is commonly used in cake-making. It is made from an alkali- bicarbonate of soda‚ and an acid- cream of tartar‚ plus a filler like corn flour or rice flour which absorbs moisture. Baking powder is a mixture of leavening agents (baking soda‚ acid salts) and inert ingredients (cornstarch‚ calcium
