separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at different rates. Hypothesis: If chlorophyll is removed from the plant‚ then the different pigments in the plant can be visible. Materials: -Spinach -Coin -Chromatography paper -Ruler

Analysis of Food Colorings by Paper Chromatography Introduction Paper Chromatography one method for testing the purity of compounds and identifying substances. This is a useful technique because it is relatively quick and requires small quantities of material. Separations in paper chromatography involve the same principles as those in thin layer chromatography. The substances are distributed between a stationary phase and a mobile phase. The stationary phase is usually

Candy Chromatography Background info: Paper chromatography is a logical technique used to separate works of a solution. Three examples of how we apply this technique to real-life would be: contaneminants in water‚ separation of plant pigmentation‚ and analysis of narcotics.

All about Distillation Distillation is a process that is used to purify a lot of substances on a domestic as well as commercial basis. It is very interesting to know about the process in detail as it is a natural process. The story begins when a liquid or solid state of mater responds to the heat in environment. The heat makes the liquid state or solid state of matter to convert into gas state. Liquid Gas (Vaporization) Solids

INTRODUCTION Distillation is a technique widely used in organic chemistry for separating compounds based on differences in their boiling points. The experiment is divided into two parts: simple distillation‚ an easy set-up where a solution or a mixture of substances with different volatility is separated through exposure heat; and fractional distillation‚ which under goes a series of evaporation and condensation process to purify more complex mixtures. Raoult and Dalton Law are the two principles

ABSTRACT Separation and identification of components of a mixture was determined by using Chromatography. The components of a mixture have different affinities for a stationary phase as well as different affinities for a mobile phase. INTRODUCTION An extremely common technique by using two chemicals and filter paper can give you sufficient information. A well-done Chromatography of dyes will provide you with enough data to determine if a liquid mixture is heterogeneous or homogenous . In a learning

Distillation of Alcoholic Beverages Pamela Mallari*‚ Symon Manuel‚ Katherine Merene and Charlene Mondelo Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Distillation is a physical process used to separate chemicals from a mixture by the difference in how easily they vaporize. This experiment aims to (1) compare the efficiency of simple and fractional distillation‚ (2) distill and calculate the % of ethanol and (3) determine the % loss in distillation. Two

FRACTIONAL DISTILLATION *Ibale‚ I.‚ Ibanez‚ E.‚ Jao‚ E.‚ Joson‚ E.‚ Juanico‚ R. 2D Pharmacy‚ Faculty of Pharmacy‚ University of Santo Tomas Abstract Distillation is a commonly used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. The product obtained by distillation is called the distillate. Volatility is the property of changing readily from a solid or liquid to a vapor. There are two types of distillation‚ simple
