A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

synthesised is only 67%-70% and a maximum 70% yield of ester usually is not considered to be acceptable for a synthesis reaction‚ instead it is considering as a poor yield of ester. The synthesised ester can only have a maximum yield of 70% because for ester in which the carboxylic acid and alcohol are sterically unhindered‚ a same ratio mixture of carboxylic acid and alcohol can only synthesis ester with a maximum yield of 70% ester as the reaction with the same ration of mixture will reach a state

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could

Synthesis As a representation of the culture of the time period‚ art enables its audience a sense of history and recollection. The pieces of work are timeless‚ precious‚ and irreplaceable‚ for they hold a significance that amazes all.

Assignment 37: Synthesis Essay As Martin Buber holds “relationship of supreme importance‚” we must hold relationships and people of supreme importance. (Littlejohn & Domenici 2007‚ p. 243). People are not objects “to be changed‚ reduced and manipulated.” (Littlejohn & Domenici 2007‚ p. 243). When we start treating people as objects we are building the I-It relationship with them. (Littlejohn & Domenici‚ 2007). This type of relationship fails to move towards value because people feel mistreated
