Biology Hl lab report: Topic: Osmosis of potatoes in different sucrose solutions. The aim of this experiment is to test whether more water moves out of a potato when it is placed in a sweeter sucrose solution than a potato in a less sweet solution. The hypothesis of the experiment is that we expect more water to move out of the potato placed in the sweet solution than the potato placed in a less sweet solution. Independent variable: concentration of sucrose‚ concentrations: pure water

CSEC CHEMISTRY NOTES ON SOLUBILITY OF COMPOUNDS IN WATER and SATURATED SOLUTION Reference: Chemistry‚ a Concise Revision Course for CXC by Anne Tindale From Chemistry for CSEC by Tania Chung-Harris and Mike Taylor Factors that influence solubility Temperature * The solubility of solids in liquids generally increases as temperature increases. * The solubility of gases in liquids generally decreases as temperature increases. (gases are less soluble in warm water than in cold water)

and Properties of Solutions INTRODUCTION The experiment aimed to describe the various ways of expressing the concentration of solutions; prepare solutions of definite concentrations from standard substances by dilution and solve problems involving preparation of solutions and their concentrations. BACKGROUND INFORMATION A solution is any homogenous mixture of two or more substances‚ the relative properties of which may vary within certain limits. The two components of solutions are the solute

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

2014 Period 4 Lab #1: Density Determinations for Solutions Theory: The density of a sample of matter is very useful when trying to find the identity of an unknown substance. The units of density are quoted in (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions in some cases. The density is different in a substance

Refining Solutions Paper How can I express myself and get the individual group to openly receive and understand the message that is being sent? That was the original problem. Some solutions would be to try and calm down before speaking to someone making sure I speak clearly and be confident when I am speaking to others not to proud but just know where I stand. Have a theme and focus on it. In certain settings I would have to speak to a specific type of audience. Although with spontaneous conversations

What are we missing about Supply Chain? Today‚ too many people think of “supply chain” tools as Warehouse Management Systems (WMS)‚ Product lifecycle management (PLM) or logistics management packages. This is a huge mistake.
