Q13.79P - Chemistry: Molecular Nature Of Matter And Change

Question

Question: What is a non-volatile nonelectrolyte? Why is this type of solute the simplest case for examining colligative properties?

Step-by-Step Solution

Answer

Answer

The non-volatile non-electrolyte molecules having covalent bond in between the atoms. The colligative properties of the molecules having covalent bond do not have the sharp change point and are easy to study.

 

Step 1: Colligative Properties

 

Solution can be formed from the dissolution of the solute in the solvent. The solute decides the nature of the solution.

Colligative Properties can be defined as the property of the molecule. It depends upon the force of attraction between the molecules. The properties depends upon the number of moles of solute in the solvent. As the dilution of the solution is increasing the properties of colligative changes.

 

Step 2: Expression to calculate the Concentration

The non-volatile non-electrolyte molecules are the molecules which have covalent bonding in the atom. The covalent bond is formed after the sharing of the electron. The colligative properties of the molecules having covalent bond do not have the sharp change point and are easy to study. The ions which dissociate into ions show and sudden change in the value which is difficult to study whereas the molecule having covalent bond shows a slight change at a period of time which can be observed or study easily.
