Title: Colligative Properties & Osmotic Pressure Background: Important terms to study from this lab assignment are colligative properties‚ membrane permeability and osmotic pressure. First‚ colligative properties are “those of a solution that depend solely on the number of solute particles present‚ not the identity of those solute particles. These properties include: vapor pressure lowering‚ boiling point elevation‚ freezing point depression‚ and osmotic pressure” (p. 17 lab manual). In this experiment

Colligative Properties & Osmotic Pressure (Lab – Chapter 13) Introduction: In this lab‚ we are going to observe the difference in freezing point between pure water and salt water. We will also observe the permeability of an egg shell membrane and dialysis tubing‚ acting in place of a human cell‚ when placed into a hypertonic or hypotonic solution. We will observe the changes in size‚ shape‚ and characteristic. Materials and Methods: First we begin this experiment by making an ice bath in

Ankur Sindhu Sep 20‚ 2011 CHEM 182-DL1 Prof.: Dr. Nidhal Marashi Lab 1: Colligative Properties & Osmotic Pressure Purpose: The purpose of this laboratory was to gain an understanding of the differences between the freezing points of pure solvent to that of a solvent in a solution with a nonvolatile solute‚ and to compare the two. Secondly‚ osmosis was to be observed to gain a proper understanding of how the principal of dialysis functions. Procedure: 1. Make

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

The calculations for colligative properties do not depend on the identity of a substance that is being used because only the amount of the substance that is used plays a role. The types of calculations that are colligative properties are: freezing point of depression‚ boiling point elevation‚ vapor pressure lowering‚ and osmotic pressure.1 Colligative properties are present in everyday life‚ such as adding salt to a boiling pot of water. By adding salt to the water‚ the boiling point of elevation

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

Cognitive Properties Ashley Weber Principles of Chemistry 2 Experiment 1 02/02/2015 Abstract: Several experiments were performed to observe the colligative properties. This includes the freezing point depression‚ and osmotic pressure. Two ice baths were made‚ one with pure water‚ the other with salt water. The lowest temperature was then record for each bath and compared. The salt water had a lower freezing point than the pure water by 2 degrees which supports the hypothesis that solutions have

within a living cell is the plasma membrane. • Hypotonic : ➢ Having a lesser osmotic pressure in a fluid compared to another fluid‚ as in a ‘hypotonic solution’ – compare: hypertonic and isotonic • Hypertonic: ➢ Having a higher osmotic pressure in a fluid relative to another fluid. • Isotonic: ➢ Having the same (or equal) osmotic pressure and same water potential since the two solutions have an equal concentration of water molecules

available energy per unit volume in terms of "osmotic pressure". It is customary to express this tendency toward solvent transport in pressure units relative to the pure solvent. If pure water were on both sides of the membrane‚ the osmotic pressure difference would be zero. But if normal human blood were on the right side of the membrane‚ the osmotic pressure would be about seven atmospheres! This illustrates how potent the influence of osmotic pressure is for membrane transport in living organisms

separate solutions into two 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
