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

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules

This is important for the students to appreciate the knowledge of chemistry that is still new for themselves. Personally‚ I think that this chapter is an interesting chapter as it revealed the way of scientist produces the material around me. It also gives me new knowledge of the uses of chemical substances that I usually found in the laboratories. I hope‚ by learning this chapter‚ I will be more interested in learning chemistry as it will help me in the future. All the equations from this chapter
