To conclude the purpose of this lab was to determine the stoichiometric coefficients in a chemical reaction using conductivity. We determine this by testing the conductivity of 9 test tubes that had certain amounts of Ag+ and the unknown ion. The balanced chemical equation between Ag+ and the unknown ion:

We determined that the value of n in the equation was 3 because the test tube with solution that produced the least conductivity was test tube 8. The volume ratio of Ag+: Bn- in the solution was 3:1 and so was the likely stoichiometric ratio. Since test tube 8 provided the least amount of conductivity that meant that the solutions combined produced a ratio that had an equal amount of reactants, thus the maximum number of ions was removed.

My calculations were accurate because each measurement was close to the sample table shown at the beginning of the lab. I followed the procedures accurately and washed the conductivity sensor with deionized water after each testing. Some sources of error that might have occurred in this lab would be that the conductivity sensor was not washed properly after each testing. Some of the ions from the previously tested test tube might remain on the conductivity sensor and passed on to the next test tube, which may falsify the data. Another common source of error would have been that the test tubes were not stirred well so that everything reacted. In order to improve this lab, I would repeat the experiment more than once to record more accurate data.
