Colligative Properties 202-NYB-05 (Group 06.) By: Jordan Hribar 1034044 Partner: Anthony Cuillierier Teacher: Daniel Baril Experiment Done: February 23rd‚ 2011 Experiment Number 2. Introduction Some of the properties unique to solutions depend only on the number of dissolved particles and not their identity. Such properties are called colligative properties. The colligative property that will be examined in this experiment will be the freezing point depression as an example

The primary challenge of inhabiting a high salinity environment is balancing osmotic pressure. Since these environments contain high salt concentrations‚ water from the cells of organisms spontaneously diffuses out of the cytoplasm in order to restore osmotic balance. This leaves cells dehydrated and thus‚ eventually causes cell death. In order to ameliorate this predicament‚ halophiles use one of two unique strategies that function to increase the osmolarity of the cell‚ both of which as illustrated

INTRODUCTION Osmosis is a passive movement of water molecules going across the partially permeable membrane. It is a very spontaneous process due to the downhill energy flow known as “water potential” by which‚ water

Colligative properties in your Coke Have you ever put salt on snow to get rid of it‚ or wondered how your car engine stays warm in cold weather? If you have‚ you’ve probably noticed that the salt quickly melts the snow‚ and you’ve wondered how the engine can stay warm‚ when the metal on the outside of the car is cold. These are just some of the many examples of how colligative properties work in our everyday lives. A colligative property is a property of a solvent that depends on the amount

categories‚ colligative properties and non-Colligative properties. Colligative properties are different from non-colligative properties because they focus on the dissolved particles‚ not the solute itself. Non-colligative properties depend on the specification of the dissolved particles and the solvent. Colligative properties are properties that depend on the dissolved solutes in the solution. There are four main colligative properties; vapor pressure‚ freezing point‚ boiling point‚ and osmotic pressure

liquid solution increases solubility. But for solubility of gas in liquids‚ an increase in temperature decreased solubility because gas evaporates as temperature increases. 2. Effect of Pressure Pressure unlike temperature has little effect on solutions unless the solute is a gas. An increase in pressure causes greater interaction between particles of the gas and the liquid‚ thus‚ increasing solubility. 3. Nature of the Solute and Solvent Nature of both solute and the solvent affect

EXPERIMENT 1 COLLIGATIVE PROPERTIES OF SOLUTIONS Date: December 03‚ 2013 Locker 21 Members: Vanessa Olga Dagondon Christine Anne Jomocan Janica Mae Laviste Nablo Ken Menez A. TYPES OF DISPERSED SYSTEMS Results and Discussion The first part of the experiment aims to differentiate the different dispersion systems. In this experment‚ three systems are introduced: true solution‚ colloidal dispersion and coarse mixture. The said three systems are classified through a property of colloids known as the

Problem How can the understanding of colligative properties be applied to making ice cream? Hypothesis Adding salt to the water lowers its freezing point (freezing point depression‚ which is a colligative property). The water will now stay liquid at lower temperatures‚ which is required to make ice cream. Procedures 1. Get all the materials : - 1/2 cup milk - 1-quart plastic bag - 1/2 cup heavy cream - 1-gallon plastic bag -

Experiment 3 Colligative Properties Freezing-Point Depression and Molar Mass By‚ Andrew Klingsporn Joby J. Chem 212 Dr. Chandana Meegoda 2/11/2009 Purpose The purpose of this experiment is to determine the Molar Mass of an unknown substance using its freezing point depression. Introduction There are two types of mixtures; homogenous and heterogeneous. Homogenous mixtures have components that are uniformly mixed‚ while heterogeneous mixtures do not. A solution is a homogenous mixture

Introduction The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in
