- Our goal for the day is to test out our apparatus with differing salt (NaCl) concentrations. We made 10 mL samples with the following concentrations: .001 M, .005 M, and .05 M.
CONTROL (distilled water) .001 M .005 M .05 M
1 4.108 M ohms 393.7 k Ohms 264.9 k Ohms 233.5 k Ohms
2 2.517 M ohms 265.5 k Ohms 266 k Ohms 26.69 k Ohms
3 2.934 M ohms 579.6 k Ohms 326.1 k Ohms 97.1 k Ohms
- With the exception of Trial 2 - .005 M reading, resistance dropped significantly with increasing concentrations of salt.
