Answer 4

As a chemist, you would use senses as the last resort. Instead, you can use fractional distillation and heat the solution to the boiling point of water, or a temperature where a phase change of sugar is unlikely but water would turn into vapor.

Answer 5

Or without even having to do change anything to the solution, you can apply Beer-Lambert's law. Place the solution into a spectrophotometer and measure your absorption values. You will have your concentrations and path lengths known. Then solve for molar absorptivity of the normal solution and only the solvent. Find the change in molar absorptivity and you will have your unique constant. Then you can refer to a table and figure out what the solute is.
