A supersaturated solution is a solution that contains more dissolved substance than a saturated solution does. This occurs when a solution is prepared at a higher temperature and is then slowly cooled. This is a very unstable situation‚ so any disturbance causes precipitation. Solubility can be understood in terms of two factors: The natural tendency toward disorder favors dissolving. The relative forces between and within species must be considered. Stronger forces within solute species

think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s death. We’ll prepare solutions of salt water to represent the sea‚ and we’ll cut up slices of potato to represent the sailor. Potatoes are made of cells‚ as is the sailor! Objective: The concentration of solute in a solution will affect the movement

so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was opened. For step two‚ a 15% glucose/1% starch solution was tested for the presence of glucose with Benedict’s‚ and we recorded the data in a table. Using more 15% glucose/1% starch solution‚ 15 mL was placed in the dialysis bag. The other end was tied‚

why we decided to focus this investigatory project on creating an eco- friendly cleaning solution. The problem of the modern world is that we have created far too much hazardous chemical since it does the daily chores‚ like that of scrubbing the floor‚ in a faster and easier pace‚ unknowing that this can harm the ozone layer. Our investigatory project aims to create an environment- friendly cleaning solution using citrus peelings and some of its extracts. With this investigation‚ we hope to find

isotonic solution do not experience osmosis. When the cell is hypotonic it has a lower concentration of solutes so water will move out of the cell. When the cell is hypertonic‚ it will have a higher concentration of solutes and water will move into the cell to attempt to reach an isotonic state. The primary purpose of this exercise is to measure the rate and direction of osmosis under different concentrations. The greater the concentration of the solute (sucrose) the faster the solution (water)

They also assure a fair and even discussion of the problem and allow all parties to play an active role in the finding of a solution. Problem Solving Sequence: Steps. 1. Define and analyze the problem. Often times‚ when one is in a conflict situation or in a position of having to deal with a problem‚ the parties involved are affected by the problem.

attempt to study the position of equilibrium. Furthermore‚ after the completion of this experiment‚ the formation of the equilibrium constant of the iron thiocyanate complex could be determined. In order to accomplish these tasks‚ five different solutions were made. Upon completion of the experiment‚ the results of the aforementioned experiments were calculated to an average of the final formation constant of 183. Introduction: The experiment for the Spectrophotometric Determination of Equilibrium

INTRODUCTION This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- . The quantitative preparation of several solutions and subsequent measurement of the solution absorbance using a spectrophotometer are the techniques that will be used in this experiment. The absorbance measurement gives the concentration of FeSCN2+. The concentrations of Fe3+ and SCN- are obtained as the difference

the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will shift to the more disordered‚ more highly dispersed solution state. I predict that as the temperature of a KCl and water mixture increases‚ then the solubility of the KCl will also increase. Variables Dependant variable

of plant cells. Water always moves from an area of high to low water potential. 2. When the two solutions on either sides of the membrane are equal and no net movement is detected‚ the solutions are isotonic. This means that the solutions have the same concentration of solutes. If two solutions differ in the concentration of solutes that each has‚ the one with more solute is hypertonic. The solution that has less solute is hypotonic. 3. This experiment was performed to measure the osmosis of small
