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

Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

CHEM 301 LECTURE Unit 1 0 . COORDINATION CHEMISTRY Factors t hat affect solubility: Common ion: decrease in solubility Complex ion: increase in solubility How does complex ion formation increase solubility? Consider the complex ion formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water

Humectants are substances used to reduce the loss of moisture. They are often found in hair and skin products. While the majority of humectants contain at least one hydroxyl group (-OH)‚ they can be separated into several different categories: alcohols‚ provitamins‚ proteins‚ saccharides‚ and many other types of molecules. Humectants in hair products can significantly impact the way our hair behaves during weather changes. Humidity draws in moisture from the air. Depending on the type of hair you
