1) Describe the appearance of each of the three curves on your graph.

PROCESSING THE DATA To analyze the relationship between conductivity and volume, use this method to calculate the linear-regression statistics for your data. Then plot the linear regression curve on your graph. Note the conductivity of pure water: 0 uS/cm Conductivity Data Table Drops 1M NaCl(aq) 1M CaCl2(ag) (uS/cm) (uS/cm) 1 150 uS/cm 110 uS/cm 2 280 uS/cm 155 uS/cm 405 uS/cm 245 uS/cm 4 516 uS/cm 340 uS/cm 3 Use 1 mL = 20 drops to Plot Conductivity (in the y axis) vs. volume of each salt solution (x axis). Do a best fit straight line through these points. Make sure to use the pure water conductivity as your zero drop. On this same graph determine the slope for both the NaCl and CaCl2, make sure to use pure water as your 0 drop. Sketch your prediction of what you would expect the AlCl3 drops to look like.

Explanation:

thats a little if u want the answer just look it up on google thats what i do haha : )
