I was showing my students how one could make an egg float by changing the density of the water surrounding the egg. We tried this experiment with the four different substances mentioned above. Our results indicated that it took 165 mL of salt to make the egg float, 305 mL sugar, 80 mL of citric acid, and 195 mL baking soda. So does that mean the citric acid is most dense of all the substances added to the water? Also, if 80 mL citric acid made the egg float, does that mean that it is the least, or the most, soluble of all the four substances? I'm having trouble understanding this.
Re: Of the four, which is most dense? Sugar? Salt? baking soda?or Citric acid?
