Calibration Curves for pH and Conductivity Continued

The remaining pH and conductivity measurements for serial dilutions 50x, 100x, 200x, 500x of the 50 mM NaCl solution, as well as for all 8 serial dilutions of the 50 mM glycine solution, were found:

Concentration of NaCl (mM) pH Conductivity (μS/cm)
50 8.827 5560
25 8.357 2924
10 8.199 1173
5 8.075 638
2.5 7.873 315
1.0 8.248 148.5
0.5 7.474 76.6
0.25 7.263 424
0.1 7.147 23.62

The following graphs demonstrate the collected data:

Concentration of Glycine (mM) pH Conductivity (μS/cm)
50 3.492 543
