special occasions like independence day. The excitement produced by fireworks like ‚ brightening the night sky and plunging it with vivid displays of colour and insignificant‚ which makes them a crowd pleaser. Behind all the excitement of fireworks‚ chemistry plays an important role in creating the vivid colours we witness lighting up the sky. The actual chemical reactions that take place in the explosions require the use of oxidisers‚ reducing agents and binders. The additions of varying metal chlorides

Initially‚ majoring in Forensic Chemistry was not my first choice. I have always been more interested in science but I never thought of actually majoring in the science field. Since I was a child I always looked forward to going to science class. In elementary school my many teachers helped me gain a love for science. But‚ it was in the sixth grade is when I decide that maybe I could see a science field in my future. My sixth grade teacher set up a dissection lab one day and we were able to pick

1. A class that I believe was most particularly significant to me is AP Chemistry. Prior to enrolling in the class‚ I was mostly breezing through school without having to put in a considerable amount of time for homework and studying purposes. A few weeks into the course however‚ I had realized that this class was not going to be even close to the ones I have taken before in terms of the rigor and depth of understanding required to succeed. Now that I have finished the course‚ albeit with a B first

The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped

Ahmed Fun Filled Hands On Science 17 January 2013 Demonstrations in Chemistry Class Chemistry is a class that a lot of college student are afraid of‚ and when I think of chemistry‚ complex equations that don’t benefit come to my mind. The reason is that all I got out of chemistry is those unbeneficial equations‚ for me at least. Also‚ I learned that H2O is water. With all those negative statements‚ I still believe that chemistry is a very important subject to understand the magic of this life and
