Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

The purpose of this lab was to synthesize indigo and an azo dye and to determine how effective each dye was to dye different types of fabrics. 0.168g of 2-nitrobenzaldehyde was dissolved into acetone along with 25 drops of distilled water and NaOH to synthesize indigo. The solution was filtered‚ and the solid indigo was placed into the filter flask to reduce indigo to leucoindigo with 10mL of 3M NaOH. The flask was heated along with sodium dithionite and distilled water added to the flask. Afiber

aspirin Intro- Aspirin is known as a pain reliever for muscle ache‚ head ache and can prevent heart attacks as well as blood clots‚ and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride

I distinctly remember having lost all feeling in my tongue and walls closing in around me. I remember sitting on my bed‚ feet dangling over the edge. Visions of my brothers‚ my nephew‚ and my unborn son flashed in my mind like lights warning me to not come any closer; for if I did‚ I would meet a similar fate. The light from the television flickered on our faces; mine blank‚ two shameful‚ and the last with rage. There is not a single noun‚ verb‚ or complex sentence in any language to describe how

Acid and Bases 1 Determining Acids and Bases SNC-2D1 April 02‚ 2013 Acid and Bases 2 Purpose The purpose of this chemistry lab is to investigate and find patterns/tendencies between substances Introduction An acid is a solution that has more free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH less than 7. A base is a solution that has less free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH of more than 7. In the late 1800s‚ the Swedish scientist Svante

Experiment 11.1 Conversion of t-Amyl Alcohol to t-Amyl Chloride Using HCL October 27‚ 2011 Purpose: Alkyl halides can be prepared from alcohols by reacting them with a hydrogen halide‚ HX (X = Cl‚ Br‚ or I). The mechanisms of acid-catalyzed substitution of alcohols are termed SN1 and SN2. The “S” stands for substitution‚ the “N” stands for nucleophilic‚ and the “1” or “2” stand for unimolecular or bimolecular. Secondary alcohols react with hydrogen halides by both SN1 and SN2
