Acids and Bases Shane Purpose- To study the relationship between pH and metabolism. 10/21/13 Materials- see attached Per. D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic

Lysergic Acid Diethylamide (LSD) was created by chemist Albert Hofmann in Switzerland while attempting to create a blood stimulant. The drug was utilized for psychological experiments for many years and this even led to the military experimenting with it as a biological weapon in the 1960’s. During the 1960’s‚ as a result to the wide dispensing of the drug for experimental purposes‚ it wound up being the “…counterculture used the drug to escape the problems of society…” (LSD: A Short History).

…………………………………………………………………………………………………………………………………………………………… Kanneliya is one of the last remaining large tracts of lowland rainforest in Sri Lanka. Wildlife Oddly lowland endemic birds such as Ceylon Rufous Babbler are missing‚ although other scarce endemic species such as the Serendib Scops Owl are present. Mammals likely to be seen are Grizzled Indian and Layard’s Striped Squirrel. The southern race of the endemic Purple-faced Leaf Monkey can also be seen. Endemic lizards seen include the Rough-nosed

This document describes the experimental process of developing a non-mechanical hot plate wind and rain sensor. It aims to discuss practical aspects of the necessary hardware to fulfil such a function and different software approaches to controlling such a system. Specifically‚ it discusses an experiment based on 30W hot plates controlled by Labview in an attempt to measure changing wind and rain conditions. It also looks at the data gathered in this instance and calibration of the sensors. Finally

nitrogens on this station. Both of these methods rely on the repulsive electrostatic interactions between the positively charged axial component and the post-switching cationic nature of the benzidine station (Figure 5.4). Deuterated trifluoroacetic acid (d-TFA) was added in the solution which resulted in the protonation of the benzidine residue and shuttling of macrocycle in to the biphenol station of the Rotaxane. This was supported by NOESY 1H NMR that showed a shift in the peaks in retrospect to

innovation comes terrible inventions such as mustard gas and the nuclear bomb. Both of these stories build on this idea of the growth of technology‚ and how it will affect our future. Ray Bradbury’s “There Will Come Soft Rains” perfectly illustrates the devastation that technology can cause. Stephen Vincent Benet’s “By the Waters of Babylon” takes place in a future post-apocalyptic Earth after a nuclear bomb has sent the human race back the the stone age. The main character John goes on a journey to

EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different pKa. The

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as
