experiment, the stock solution was prepared with a known initial volume, a known initial concentration, and a known final volume. The final concentration was calculated using the dilution equation, which showed how dilute or how concentrated the solution was as the experiment progressed. To form a solution at a certain concentration, such as a more diluted solution for an experiment, a solute is dissolved in a solvent thoroughly, and brought to the required volume of solution. Throughout the experiment

supersaturated solution. 2. The solution is supersaturated because there is more solute than the maximum at the temperature at the end of Step 2. There were 5 grams of solute in the 10 grams of water. According to the given solubility chart for sodium sulfate, in order for the solution to be saturated at the given temperature (approximately 100°C because the water was nearly boiling), the solution could hold about 4.2 grams of solute. Because there was more than 4.2 grams, the solution was supersaturated

Creating Solutions of Standard Molarity Krishnaben Patel Katherine Asibal CHEM 1251L-027 10-1-2014 Introduction: In this experiment, a series of 〖Cu〗^(2+) solutions of different concentrations were prepared using the dilution technique. The principles of spectroscopy of and appropriate usage of Spec 20 was taught. The spectrophotometer instrument was used to measure the amount of light that passes through a solution. Beer-Lambert law was applied to determine the concentration of 〖Cu〗^(2+) in an unknown

Investigation of Factors Affect Osmosis in Potatoes  Aim  The aim of the following experiment was to investigate the effect of  varying the concentration of sucrose solution on osmosis in a potato.  Preliminary Experiments  One preliminary experiment was done before the main experiment. From  the preliminary, we were trying to find out how osmosis actually  occurred in potatoes, and gave us a vague idea on what the main  experiment would be like.  This preliminary will aid my prediction

There are many possible solutions that have been attempted to try and stop forced labor and while some have helped a little none of them have been able to make the problem go completely away. These solutions have a better chance at working and getting rid of the forced labor problem if they were combined. There is no one set solution to any problem, there are multiple that needs to be put together to make one integrated solution. The possible solutions are all really good ideas they are just not

this lab was to create four solutions of the same components and different concentration. I found the concentration in Molarity (mol/liter). I would dilute a solution to create new solutions, using the formula M1xV1=M2xV2 where M=molarity and V=volume. In this lab, there were four solutions, Solution A, Solution B, Solution C, and Solution D. The solute or substance that dissolves was sugar and the solvent or substance that the solute dissolves in was water. For Solution A, I weighed 3.42 g sugar

In this experiment, the concentration of an unknown permanganate solution will be determined. Spectroscopic techniques will be used to measure various known concentrations of permanganate solutions to create a calibration curve for the absorbance of light vs. the concentration and will be used to determine the unknown concentration1. Introduction In order to perform this experiment, proficiency with using spectrometers, burettes, volumetric flasks, weighing by difference, and making a hot-water bath

of salt solution concentration on the mass in russet potatoes? Background Osmosis is a process which molecules of a solvent pass through membrane from a less concentrated area to a more concentrated area until it equalize the concentration on both side. Isotonic, hypertonic, hypotonic solutions can be generally used to compare concentration of a solute in two solutions. Hypertonic solution is when one of two solution has a higher concentration of a solute and we call this type of solution plasmolyzed

In this lab, lab 4.3 Comparing the Concentrations of Saturated Solutions, we set out to find and compare the solubilities of two solids in water. In addition, we tested if solubility is a characteristic property of a solid in a given liquid. This lab allowed us to test and use a reliable way to measure the solubility of a solid. This lab can be replicated for any solid with the same procedure, thus it gives us a method to calculate solubility. The two solids we tested in this experiment were NaCl

Title: The effect the molarity of sucrose solution has on osmolarity Introduction: Passive transport occurs when substances move from high concentration areas to a lower concentration region. Both Diffusion and Osmosis are examples of passive transport, however, osmosis is when water molecules move across a selectively permeable membrane. The plasma membrane, being a thin barrier to outside environment, is a selectively permeable membrane. Thus, it only allows certain particles to enter or exit
