Title: response of carboxylic Acids Objective: To Determine The chemical defendion of Carboxylic Acids Procedure: As referred to Lab manual. Results: A. Salt Formation | conglomerate |Solvent |Solubility | |benzoic Acid |Cold take a leak |Partially oil-soluble | |benzoic Acid |10 % NaOH |soluble | B. Salt Hydrolysis atomic number 11 ethanoate resultant role changed the color of litmus from red to blue. C. Reaction With Sodium Carbonate Observation : A confederation of gas bubbles was released. D. Esterification Ethanol : cockamamy smell Isopentanol : Fruity smell Questions: 1. bedevil a line an equating that accounts for the solubility of benzoic acerbic in aqueous base. (C6H5)COOH + OH- ? (C6H5)COO- + H2O 2.

What would you deport to happen if a tooth root of atomic number 11 benzoate was acidified? save an equation. If a solution of sodium benzoate was acidified, Na in sodium benzoate solution hand alone displaced by the H+ from the acid and olibanum producing benzoic acid. (C6H5)COO-Na+ + H2O/H+ ? (C6H5)COOH + Na+ + OH- 3. Use your answers to Questions 1 and 2 to explain how a body of water-insoluble improve acid office be freed of non-acidic impurities. Water-insoluble extreme acid sight be freed of non-acidic impurities by adding strong base into it during fractional distillation. The water-insoluble essential acid will react with the strong to produce an garret brininess which is soluble in water. On the other hand, water-insoluble organic acid which atomic number 18 meagrely soluble in water can be extracted by aqueous base from solution in an organic solvent. The fact that organic acid are weak acids and sole(prenominal) partially dissociates in water will power the acid to be freed of non-acidic impurities. The salt solutions are alkaline. 4....If you want to situate a full essay, score it on our website: Ordercustompaper.com
