Conductivity vs Molarity Essay Example for Free
Conductivity vs Molarity Essay accession Athetles consume Gatorade to replenish the electrolytes lost through sweat. Since Gatorade has a high concentration of solutes such as electrolytes it all toldows for the sickening system to respond faster to changes in the body. Electroyltes are molecules that stooge dissociate into ions and conduct electric 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 currents in there solid form they are put in a solution to dissociate. The mathematical function of Lab 32 was to determine the effect that the concentration of a solue has on the conductivity of an electrolytic solution. If NaCl is added to water system system to create an electrolytic solution then it leave create a stronger electrical current than distilled water because NaCl is a strong electrolyte that can conduct electricity well due to its abi lity to dissociate into ions. Materials and Methods In order to run for the effect that the concentration of a solute has on the conductivity of an electrolytic solution. Four beakers were modify with 100 ml of distilled water.A conductivity tester was then put into the first beaker of water to test for the conductivity of the control. 20 grams of coarseness was then weighed on a scale, 2g of salt was placed in 1 beaker to create a . 346 molar solution. 5g in the next to create a . 865 molar solution and 10g on salt was placed in the last beaker to create a 1. 73 molar solution. The solutes were stirred until they were wholly dissolved in the water. The conductivity tester was again used, and placed into the 3 beakers to test for the conductivity. For each beaker the conductivity was recored.After the data was recored the materials were put away and post lab questions were answered. Trends For both trials there was a crispy increase in conductivity from the control to beaker 3 (filled with 5g of NaCl). But the level of conductivity in all the beakers never exceded a conductivity of 10. Discussion The purpose of the lab was in fact met. As expecteted the beaker that had 10g of salt had a higher conductivity than the control.There was a direct relationship between concentraion and conductivity and the intial supposal was supported, as seen in Graph 32. . For example a solution with . 346 molarity had a conductivity of 7. indeed as concentration increased so did conductivity. However a solution with a molarity of . 865 had the similar conductivity of a solution with a molarity with 1. 73, because NaCl doesnt have the sea of electrons that metals do. There were internal errors in the lab. Since the placement of the conductivity tester was not always placed in the homogeneous reason of each solution the data may be inclaclusive.Different conductivity levels could have been retrived at several(predicate) depths in the solutions. Also the size of the bea ker would come into factor because the size determines the depth. When approcaching the lab again all the same size beakers and equipment should be used. This would allow for the the conductivity to be the tested in the same depth for to a greater extent accurate results. This lab clearly shows how a higher concentration of solutes in a solution, can and will increase the electrical current with in the body.
