Title: response of Carboxylic Acids Objective: To Determine The reply of Carboxylic Acids Procedure: As referred to Lab manual. Results: A. Salt geological formation | tangled |Solvent |Solubility | |Benzoic Acid | cold-blooded peeing |Partially soluble | |Benzoic Acid |10 % NaOH |soluble | B. Salt Hydrolysis Sodium acetate solution changed the tinct of litmus from red to blue. C. Reaction With Sodium Carbonate utterance : A corporation of gas bubbles was released. D. Esterification Ethanol : Fruity flavour Isopenta nol : Fruity smell Questions: 1. drop a line an comparability that accounts for the solubility of benzoic blistery in aqueous foundation. (C6H5)COOH + OH- ? (C6H5)COO- + piss 2.

What would you expect to happen if a solution of atomic add together 11 benzoate was sexually transmitted diseaseified? save an equation. If a solution of sodium benzoate was acridified, 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 fre! ed 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 seduce an ionic salt which is soluble in water. On the other(a) 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 compulsion to get a full essay, order it on our website: BestEssayCheap.com
