Title: response of Carboxylic Acids Objective: To Determine The reply of Carboxylic Acids Procedure: As referred to Lab manual. Results: A. Salt shaping | tangled |Solvent |Solubility | |Benzoic Acid | unwarmed peeing |Partially soluble | |Benzoic Acid |10 % NaOH |soluble | B. Salt Hydrolysis Sodium acetate solution changed the colour of litmus from red to blue. C. Reaction With Sodium Carbonate expression : A corporation of gas bubbles was released. D. Esterification Ethanol : Fruity timber Isopentanol : Fruity sme ll Questions: 1. drop a line an equating that accounts for the solubility of benzoic blistery in aqueous stand. (C6H5)COOH + OH- ? (C6H5)COO- + piddle 2.

What would you expect to happen if a solution of atomic come 11 benzoate was erosiveified? save an equation. If a solution of sodium benzoate was ditified, Na in sodium benzoate solution leave 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 water-insoluble perfect acid office be freed of non-acidic imp urities. Water-insoluble organic acid! can be freed of non-acidic impurities by adding strong base into it during fragmentary distillation. The water-insoluble organic acid result react with the strong to unveil an ionic salt which is soluble in water. On the new(prenominal) hand, water-insoluble organic acid which are slightly 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 cause the acid to be freed of non-acidic impurities. The salt solutions are alkaline. 4....If you loss to get a full essay, order it on our website: OrderCustomPaper.com
