**Conductivity of Different Salt Solutions**By: Jennifer Stall Amanda Leonard Jason Toon Marina Korolis Kris Mason Dan Pellegrini**Our Goals for this Experiment**• Explore the property of conductivity of solutions • Formulating hypotheses, predicting relationships and gathering data • Use mathematics to interpret graphical data • Discover the role mathematics plays in the scientific process**Procedure**• First, we prepared 1M solutions of potassium chloride and magnesium nitrate. • We made a prediction about the conductivity of each solution • We started with a beaker -full of water, and measured the conductivity with each progressive drop • Finally, we analyzed our data**How to combine Math and Chemistry**• Since we made graphs of conductivity vs. volume, and we found the relationship to be linear, students can easily find the slope, x- and y- intercepts, and equation of the best-fit line • We can describe a mathematical relationship between the conductivity and the number of ions in solution**What we would do differently next time**• We discovered afterwards that using two different anions introduced another variable which invalidated our hypothesis • We should use solutions that contain the same anion but different cations (i.e. sodium chloride, calcium chloride, aluminum chloride) • For more information, refer to this lesson
