The effect of changing volumes of NaF added to 1mL of 35 °C yeast on the level of respiration in the solution, as measured by the degree of colour change after 10 minutes. | Degree of colour change in yeast solution at 35 °C after 10 minutes | Concentration of NaF drops in the yeast solution (+/-1 drops)| Group 1| Group 2| | Trial 1| Trial 2| Trial 3| Trial 4| Trial 5| Trial 1| Trial 2| Trial 3| Trial 4| Trial 5| A=0 drops| 1| 2| 2| 2| 2| 1| 1| 1| 1| 1|

Observations:
-As NaF became more concentrated in the solution, it gradually became closer to purple/blue (darker colour) - As NaF became less concentrated in the solution, it gradually became closer to peach/colourless (lighter colour)
