Chemistry Coursework – Titration Background Science A titration is the neutralisation of an acid or an alkali. To achieve this‚ one must be added to the other in a specific amount‚ strength and concentration. A substance is neutral when its pH is 7. It is most acidic closer to 0 and is most alkaline closer to 14. 28492453194050 0 7 14 595423979670

Kayla Adkins Forensic Chemistry Exam 2 I have been honest and observed no dishonesty. 1. In specific detail‚ describe a published procedure for the definitive identification of Heroin utilizing gas chromatography-mass spectroscopy (GCMS). Heroin is a white crystalline powder with no odor and a bitter taste. It is a derivative of morphine in that the –OH (hydroxyl group) is replaced by an acetyl group‚ -OCOCH3 and has a molecular formula is C21H23NO5 with a molecular weight of 369.42

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

took my first chemistry class I became mesmerized with the field of chemistry. The idea that I could start with one molecule and change it into a completely different compound both fascinated and thrilled me. I was at a predicament‚ on one hand I wanted to study medicine to help people‚ but I was far more interested in and passionate about the chemical processes and reactions. This changed when I took my first organic chemistry class. I want to make a career by applying chemistry to medicine and
