Title: response of Carboxylic Acids Objective: To Determine The reception of Carboxylic Acids Procedure: As referred to Lab manual. Results: A. Salt institution | tangled |Solvent |Solubility | |Benzoic Acid | frozen peeing |Partially soluble | |Benzoic Acid |10 % NaOH |soluble | B. Salt Hydrolysis Sodium acetate solution changed the contort of litmus from red to blue. C. Reaction With Sodium Carbonate bill : A corporation of gas bubbles was released. D. Esterification Ethanol : Fruity sense of smell Isopentanol : F ruity smell Questions: 1. drop a line an equating that accounts for the solubility of benzoic blistery in aqueous meanspirited. (C6H5)COOH + OH- ? (C6H5)COO- + water 2.

What would you expect to happen if a solution of atomic bit 11 benzoate was panellingified? save an equation. If a solution of sodium benzoate was mordantified, 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 offi ce be freed of non-acidic impurities. ! Water-insoluble organic acid can be freed of non-acidic impurities by adding strong base into it during aliquot distillation. The water-insoluble organic acid volition react with the strong to enkindle an ionic salt which is soluble in water. On the separate 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 indigence to get a full essay, order it on our website: BestEssayCheap.com
