Introduction: Athetles consume Gatorade to replenish the electrolytes lost through sweat. Since Gatorade has a high concentration of solutes such as electrolytes it allows for the nervous system to respond faster to changes in the body. “Electroyltes are molecules that can dissociate into ions and conduct electrical currents” (EduChange 2002). These molecules‚ can move freely‚ once dissociated into ions allowing for there to be a electrical current. Because elcetroyltes can not conduct electrical

Determining the Molarity of Acetic Acid in Vinegar Abstract This experiment was done to determine the molarity of acetic acid in vinegar. The acetic acid in vinegar was titrated with a strong base sodium hydroxide to determine the equivalence point of this chemical reaction. The indicator phenolphthalein was used because the moment it changes color is on the basic side of the pH scale. To insure the experiment was done with the most accuracy‚ the two conductors of this experiment took three

Research: The word density means the degree of compactness of a substance. There is density in everything in your everyday life (matter.)The formula to find density is d=m/v.The density of solids and liquids is usually stated as g/cm3‚ while gases are usually stated as kg/m3. A real life example of density would be that ice floats on water because it is less dense than water‚ or it sinks because it is more dense than water. The only substance that breaks this rule is ice. Archimedes was

Molrity Analytical Molarity is the total number of a solute‚ regardless of its chemical state‚ in one liter of solution • describes how a solution is prepared(recipe) 98.0 g H2SO4 dissolved in water diluted to 1.0 L. 1.0 M H2SO4 Equilibrium Molarity or species molarity is the molar concentration of a particular specie in the solution. • requires a careful analysis on how solutes behave when it is dissolved in solvents 1.0 M H2SO4 (AM) 0.0 M H2SO4 (EM) Species molarity due to dissociation:

2016 In This experiment we used potassium permanganate (KMnO4) as our titrant and our titrand was oxalic acid (H2C2O4● 2H2O). The objective of the experiment was to titrate the solutions to determine the molarity of potassium permanganate. We had to dilute the stock solutions to a specific molarity for the experiment. Using the same method‚ an unknown solution called “120x” was titrated to find its percentage of oxalic acid. Introduction The purpose of the experiment was to use volumetric analysis

Chemistry Assessment Practical and Report: Introduction: The experiment was conducted to find the unknown molarity of HCL. The unknown molarity of HCL was found by the use of the titration method and then comparing the results between the titrant and analyte HCL solutions. Molarity is a concentration unit‚ it is defined by the number of moles the total volume of the solution. This experiment included a process called titration‚ used to work out the unknown concentration of a known substance.

PHYSICAL PROPERTIES: DENSITY Introduction According to the definition Density is the physical property that allows us to compare the mass of substances for a specific volume. In this Lab activity that took place in Deree College‚ Agia Paraskevi Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means‚ how we can measure it‚ how useful it is‚ what is the difference between density of solids and liquids

Throughout the lab I found out that both of the small and large silver rod‚ do not have the same density‚ and also found out that the gold rod is not real gold. My hypothesis is that since‚ the large and small silver rod has about the same density I believe that they would have about the same amount of volume. They both might displace the same amount

10/1/13 Cubs Density The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density.
