Procedure

1.  Collected the materials indicated and connected the GLX to the conductivity sensor

and then to the computer.

2.  Began a new experiment on Data Studio Program

3.  Obtained 9 test tubes and labeled them 1-9

4.  Placed each test tube on a rack

5.  For each test tube we added the amount shown in table 1 of AgNO3 and also an unknown solution

6.  Placed a small piece of parafilm on the top of each test tube

7.  Then placed my thumb on the mouth of the test tube and began to shake it. We did this for every test tube.

8.  Allowed the mixtures to settle

9.  Rinsed the conductivity sensor with deionized water

10.  Placed the conductivity sensor in the first test tube, waited 30 seconds, then recorded the conductivity

11.  Repeated step 10 for every test tube

12.  Between each test tube, rinse the conductivity sensor with deionized water and drained it in the waste beaker (100mL beaker).

13.  Measured the conductivity and recorded each on table 2
