Mario Renteria Mrs. Weathers Chem 04a 27 Jan‚ 2012 Lab Report Introduction: A popular technique in separating components of a mixture is paper chromatography. We use paper chromatography to separate mixtures and isolate there components to collect them individually. In this experiment‚ we will use acid- base indicators to help determine the unknown mixture. Acid- base indicators will change in color when the presence of pHs rise and fall when acids or bases are added to a solution. After setting

For our final essay‚ we are given two articles in order to examine and compare with one another. The first of the two selections is “Separating” by John Updike. The second piece of reading is entitled “Everyday Use” by Alice Walker. Both articles were written in the early 1970s‚ and are both from the short story genre; However‚ both authors had different ways of thinking and expressing themselves due to their differences in age‚ gender‚ ethnicity‚ race‚ and personal influences. Nevertheless‚ during

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

Separating a Single World Current education systems put extra emphasis on classroom time‚ instruction‚ and behavior. This extra emphasis leads to the involuntary creation of a unique world where certain educational functions‚ events‚ and thought only happen in the classroom. Even more extreme‚ student only learn in the classroom. Classrooms now put way to much stress on the student and leads to no functional learning outside of the space. You get beat down so hard in the class with information and

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

Separating Water Soluble and Acetone Soluble Inks through Chromatography Abstract: Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble
