Document Summary
Figure 1: potentiometric titration of unknown halide solution using silver nitrate and derivative curve of trial 1 using 2, 3, and 5 data point average. Figure 2: potentiometric titration of unknown halide solution using silver nitrate and derivative curve of trial 2 using 2, 3, and 5 data point average. Figure 3: potentiometric titration of unknown halide solution using silver nitrate and derivative curve of trial 3 using 2, 3, and 5 data point average. Table1: volume of agno3 at 1st endpoint and 2nd endpoint in titration #1, 2 and 3. Precision of the volume of agno3 at 1st endpoint: Volume of distilled water added = vw = 90. 00 0. 50 ml. Volume of unknown solution added = vu = 10. 00 0. 04 ml. Sample uncertainty error calculation: s y= (sa)2+(sb)2 s= 0. 04 2+0. 502=0. 50 ml. Concentration of stock agno3 solution = cagno3 = 0. 1000 0. 0005 m. Volume of agno3 required to reach = vagno3 = 0. 008727 0. 000097l.
