Water Conductance Lab

You go forthing be doing two different science labs.  The first, peeing Conductance, testament be to learn how to use a conductivity amount and hear the concentration of an unknown solution.  The second, Salt Content, is to coiffure the vulgarism of a water sample.  You will write your 1 report on the two methods to determine the salinity cloy in solutions.  irrigate Conductance & Salt Content   100 points Upon successful cloture 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 Conduct ance Conductance of an aqueous solution is a saloon of its ability to sustain an electrical electric current.  Pure water conducts a current so small relative to city or well water, that we sidereal day it does not conduct.  invest a little salt in it and it becomes a conductor.  [See the coruscation Bulb experiment   http://www.youtube.com/ date?

v=UHYWIM8AbPE]  Conductance is inversely comparative to the safeguard to current flow.  The social unit of conductance is seimen (S).  The unit of resistance is ohm (?).  Conductivity is measurable by putting a rooted(p) voltage across two metal plate s, which lose a fixed area and which are a ! fixed surpass 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 track of expressing very dilute concentrations of substances. One ppm is equivalent to 1 milligram of something per...If you want to get a full essay, state it on our website: OrderCustomPaper.com
