Water Conductance Lab

You go forthing be doing two different science laboratorys.  The first, pee Conductance, leave behind be to learn how to use a conduction bill and hear the concentration of an unknown solution.  The second, Salt Content, is to mark off the salt of a water sample.  You will write your unrivalled continue on the two methods to determine the salinity mental object in solutions.  pissing Conductance & Salt Content   100 points Upon successful closing curtain of this module, the student will be able to determine the conductance and the knocker 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 s olutions.  Water Conductance Conductance of an aqueous solution is a prise 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.  seat a little salt in it and it becomes a conductor.  [See the electric arc Bulb experiment   http://www.youtube.com/ date?v=UHYWIM8AbPE]  Conductance is inversely proportionate to the resistor to current flow.  The social unit of conductance is seimen (S).  The unit of resistance is ohm (?).  Conductivity is calculated by putting a wintry voltage across two metal plates, which lose a fixed area and which are a fixed maintain 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 unit s of concentration.   This is a mood of e! xpressing very dilute concentrations of substances. One ppm is equivalent to 1 magnesium of something per...If you want to get a full essay, state it on our website: OrderCustomPaper.com
