write chemistry lab report about (separation and purification scheme)


Question descriptionthe mixture was (50% benzoic acid, 40% benzoin, 10% dibromobenzene)

the report must include (introduction, observation, discussion, conclusion)

the mixture i used = 0.503g

methylene chloride = 4 ml

sodium hydrous carbonate =4 ml

then i removed the aqueous layer to another test tube

6M HCl was to the aqueous layer then saturated sodium chloride

weight of the filter paper with benzoic acid (0.172 + 1.868)

for the organic layer i added ethanol to recrystallize (benzoin, dibromobenzene)

the filter paper for the organic component + crystal (0.180 + 0.23)
