Experiment 28: The reaction of Butanols with Hydrobromic Acid Pre-lab Objective: The objective of this experiment is to synthesize 1-bromobutane and 2-bromobutane with different catalyst:substrate ratios to determine which ratio is the most economically favorable. Discussion: In this experiment‚ 1-butanol or 2-butanol will be converted to the corresponding alkyl bromide with HBR‚ while using sulfuric acid as a catalyst. The sulfuric acid will accelerate the chemical reaction with being consumed

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight

Acid Determination of Vitamin C Tablets and Salt Solutions Chem 1290-016 03-05-2010 ------------------------------------------------- Purpose: The purpose of this lab was to use acid-base titrations to find the mass percent of ascorbic acid in a Vitamin C tablet. A known concentration of sodium hydroxide was used and the value found was compared to the stated amount of ascorbic acid listed on the vitamin container. Also in this lab the acidity of different salt solutions were tested using

Post positivist approach is a metatheoretical stance philosophically rooted in positivism. Whereas positivists believe in the existing reality apart from our own perception of it and the importance of empirical observation as well as rock-solid general laws‚ post positivists share some similarities with a softer‚ amended approach. Realist and the social constructionist are both taken as ontology by post positivist researchers in communication discipline. That is‚ it can be true that post positivist

I will admit that I am rather new to the discussion on bigotry‚ privilege‚ and the various -isms. I was speaking with a female friend of mine a few months ago‚ and I remarked that women‚ on average‚ are less able to compartmentalize their emotions than men. She was (justifiably) irate‚ and I qualified myself. You see‚ I had never been explicitly exposed to the socially-propagated idea that women are emotionally unstable. When I found out‚ I felt rather embarrassed in not only being sexist‚ but
