Explanation:
Calcium chloride is an ionic compound as it is formed by transfer of an electron to each chlorine atom.
So, being an ionic compound calcium chloride is able to dissociate completely into water.
Hence, the dissociation reaction will be as follows.
Since, two electrons has been lost by single calcium atom. Therefore, calcium atom will have a charge of +2.
Thus, we can conclude that the charge on the calcium ion, in elementary units is +2.
Explanation:
A non-electrolyte is defined as a solution which does not contain any ions and hence, it is unable to conduct electricity.
For example, when a non-polar substance like is dissolved in water then it will not dissociate into ions.
As electricity is the flow of ions or electrons. So, a non-electrolyte solution is not able to conduct electricity.
Similarly, a compound that is insoluble in water will not dissociate into ions. Hence, this type of solution will not be able to conduct electricity.
