Why are most solid ionic compounds electrically nonconductive, whereas aqueous solutions of ionic compounds are good conductors? would you expect a liquid (molten) ionic compound to be electrically conductive or nonconductive? explain

Explanation:

It is known that for a substance to conduct electricity it is important that there must be flow of electrons or ions.

In solid compounds, molecules are not present in the form of ions. As they are held closer to each other due to strong intermolecular forces of attraction.

Hence, a solid ionic substance doe not have flow of ions or electrons in solid state. Therefore, they are non-conductive in nature.

Whereas when an ionic compound is dissolved in a solvent then it will dissociate into ions due to which there will be flow of ions and electrons. Hence, aqueous solutions of ionic compounds are able to conduct electricity.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

i think it is true since you can test the answer and can use observations to complete it.
