Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly

Electrophilic Aromatic Substitution Objective The objective of this experiment was to illustrate electrophilic aromatic substitution by synthesizing p-nitroanilide (as well as ortho) from acetanilide by nitration. The para form was separated from the ortho form based on solubility properties using recrystallization techniques. Synthetic equations: Physical Properties & Hazards of Reagents/Products: (all taken from Sigma-Aldrich website) Acetanilide MM = 135.16 g/mol Melting point =

“Remember” is a sonnet by a poetess of Victorian England‚ Christina Rossetti. The poem was written in 1849 but was first published in 1862 in “Goblin Market and Other Poems” by Rossetti (Petacovic‚ 2009).
