I did an experiment in the lab called Potentiometric Determination of Fluoride. There is a series of questions that i need help to answer:

1) Explain the effect it would have if no constant ionic strength is maintained when performing potentiometric measurements.

2) A standard solution of NaF 1.00x10-3 M read -0.230V. The solution of an unknown read -0.300V. What is the [F-] in the unknown solution?

3) What is the change in the measurement of the potential if a solution of 1.00x10-3 M NaF is exchanged for another solution of 1.00x10-4 M NaF?
