09/18/2012 09/19/2012 Title: Separation of Mixtures and Solids Purpose: The purpose of this experiment was to practice the process of separating mixtures of different solids. Procedure: This experiment consisted of different processes to separate a mixture of solids into the four individual solids: sand‚ benzoic acid‚ iron fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up all the

EXPERIMENT 2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain

Both anomers of D-glucose have a similar structure with a molecular formula of C6H12O6.Within normal conditions; D-glucose exists as a mixture of cyclic hemi-acetals (ring) and open-chain (acyclic) form within aqueous solution. The ring of D-glucose consists of 5 carbons and oxygen which each carbon is linked to a hydroxyl group with exception of the 5th carbon which is linked to a methyl-hydroxyl
