concentration of biological system is usually preferred as the pH system‚ which determines the pH level of dilute aqueous solutions. In this laboratory‚ the data collected from the experiment will be used to graph the titration curves which help to identify an unknown amino acid. IntroductionAmino acids are simple monomers which are strung together to form proteins. Amino acids play a key cellular role in structure and function. Proteins themselves participate in nearly every physiological event in the cell

Unknown Organism Report Unknown Organism # 4 Klebsiella pneumonia Klebsiella pneumonia has a rod gram stain with the agar slant cultural characteristics being slimy‚ white‚ somewhat translucent‚ raised growth. It is small gram-negative coccobacilli that can cause lobar pneumonia. The litmus milk reaction is acid‚ gas‚ and curd with a variable reaction. Klebsiella can grow either in the presence or absence of oxygen because of its nature of being a facultative anaerobe. Oxygen is a preferred energy

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion

The book‚ “Adventures in the Unknown Interior of America” was translated and edited by Cyclone Covey in 1961. It is a semiofficial report (more like a personal diary) written by Alvar Nuñez Cabeza de Vaca to the King of Spain regarding the Narváez expedition. The original report by Cabeza de Vaca was titled‚ La Relación (1542) along with supplemental material called the Joint Report was used to describe the epic events that happened on the expedition. Cabeza de Vaca was born in 1490 in the town

chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds were mixed together by the

The aim of this experiment was to calculate the concentration of an unknown solution of Sodium Hydroxide (NaOH) by titrating it with Hydrochloric Acid (HCl) and to identify any possible sources of error. A colour change from pink to yellow signified the end of each individual titre as the NaOH had been neutralised. Experimental: Method: Firstly two solutions were prepared to show the colour of the Phenol Red indicator in acid and alkaline conditions. These colours were then used to determine the

English Essay - Belonging Question - Belonging has been said to shape our identity. How does our sense of belonging shape who we are as individual? An individuals relationship with others and the world creates a sense of belonging and additionally shapes a sense of identity. This is demonstrated in the poems "Migrant Hostel"‚ "St Patrick’s College" by Peter Skrzynecki and a novel "Tea With Arwa" written by Arwa El Masri. Both text illustrate that belonging is a notion that shapes an individual’s
