Thank you for this informative article. I would like to add some points to readers about the difference between salt and sugar in chemistry:
When the salt is dissolved in the water, an ionic solution is formed with two types of electrolytes: positive electrolytes(+) and negative electrolytes(-). and in this solution the number of negative electrolytes is equal to the number of positive electrolytes which means that the total charge of the solution is zero.

• The cation Na+ Indicates that the sodium atom has lost one electron:
  Na======== (Na+) + 1e-
• The anion Cl- indicates that the chlorine atom earn one electron:
  Cl + 1e- ======= Cl-
  As a result of positive + and negative - charge moving in two opposite directions within the solution, this solution conduct electrical current. Unlike molecular solutions such as water solution + sugar, the electric current can not be transmitted because there are no ions in the solution.
  
  Have a nice day, keep on writing good articles, i wish you a good luck
