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

What would you expect to happen if a solution of atomic subjugate 11 benzoate was vinegarishified? save an equation. If a solution of sodium benzoate was acidicified, 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 off ice be freed of non-acidic impurities. ! Water-insoluble organic acid can be freed of non-acidic impurities by adding strong base into it during divisional distillation. The water-insoluble organic acid leave alone react with the strong to go an ionic salt which is soluble in water. On the other 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 necessitate to get a full essay, order it on our website: BestEssayCheap.com
