Water Conductance Lab

You go forthing be doing two different research laboratorys.  The first, water system Conductance, go out be to learn how to use a conductivity step and hear the concentration of an unknown solution.  The second, Salt Content, is to see to it the obscenity of a water sample.  You will write your unmatched extend on the two methods to determine the salinity field in solutions.  urine Conductance & Salt Content   100 points Upon successful destruction of this module, the student will be able to determine the conductance and the flavor and soul salt content of unknown sample. Changes in this lab: none  You will be doing two different labs.  The first, Water Conductance, will be to learn how to use a conductivity meter and determine the concentration of an unknown solution.  The second, Salt Content, is to determine the salinity of a water sample.  You will write your one report on the two methods to determine the salinity content in solutions .  Water Conductance Conductance of an aqueous solution is a bankers bill of its ability to sustain an electrical electric current.  Pure water conducts a current so small relative to metropolis or well water, that we sidereal day it does not conduct.  coif a little salt in it and it becomes a conductor.  [See the swooning Bulb experiment   http://www.youtube.com/ date?

v=UHYWIM8AbPE]  Conductance is inversely proportionate to the enemy to current flow.  The social unit of conductance is seimen (S).  The unit of resistance is ohm (?).  Conductivity is metrical by putting a quick-frozen voltage across two metal plates, which lose a fixed! area and which are a fixed outstrip apart. The electric current that flows between the two electrodes varies as the conductivity of the solution changes. This variation in the flow of current is measured by a conductivity meter and is displayed as a conductivity reading. You will be using ppm (part per million) for units of concentration.   This is a agency of expressing very dilute concentrations of substances. One ppm is equivalent to 1 mg of something per...If you want to get a full essay, state it on our website: OrderCustomPaper.com
