Question

c) Conductivity of Sports Drinks Conductivity Brand of Sports Drink 2.12 Gatorade ms Powerade ms a.81 i) Approximately what molarity of NaCl does the conductivity of the sports drink correspond to? (refer back to your conductivity values from section 4b) ii) Write down the ingredients from the label of one brand of drink: Gatorade: water, Sugar Dextrose, Ctric audi Sodiom Citrate Natural flavor, Yellow 5, MonoPota ssium phosphate, gum ly cerol ester of rosin arabic ble for the electrical conductivity? Explain.

i) approximately what molarity of MaCl does the conductivity of the sports drink corresponds to?

Conductivity of 0.10 M NaCl : 1.131 mS

Conductivity of 0.010 M NaCl: 0.41 mS

Conductivity of 0.010 M CaCl2 : 2.07 mS

Answer 1

mS is the unit of Conductance, not Conductivity, the unit of Conductivity is S/m.
