Title: response of Carboxylic Acids Objective: To Determine The reply of Carboxylic Acids Procedure: As referred to Lab manual. Results: A. Salt validation | tangled |Solvent |Solubility | |Benzoic Acid | chilly peeing |Partially soluble | |Benzoic Acid |10 % NaOH |soluble | B. Salt Hydrolysis Sodium acetate solution changed the rubric of litmus from red to blue. C. Reaction With Sodium Carbonate reflexion : A corporation of gas bubbles was released. D. Esterification Ethanol : Fruity thwack Isopentanol : Fruity sme ll Questions: 1. drop a line an compare that accounts for the solubility of benzoic blistery in aqueous tie-up. (C6H5)COOH + OH- ? (C6H5)COO- + piddle 2. What would you expect to happen if a solution of atomic chip 11 benzoate was doseified? save an equation. If a solution of sodium benzoate was harshified, 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 impurities. Water-insoluble organic acid can be freed of non-acidic impurities by adding strong base into it during incomplete distillation. The water-insoluble organic acid entrust react with the strong to puddle an ionic salt which is soluble in water. On the separate hand, water-insoluble organic acid which are slightly soluble in water can be extra cted by aqueous base from solution in an org! anic 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 essential to get a full essay, order it on our website: BestEssayCheap.com
