why do molten ionic compounds conduct electricity?
31727
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Yes, it may. Because if melting an ionic compound requires extreme temperature, to vaporize it you will need superlative amount of heat energy. ... So, there you have it – ionic compounds can exist as solid, liquid and gas depending on the conditions they are exposed to.

Ionic compounds have ionic bonds and molecular compounds have covalent bonds. ... Ionic compounds have higher melting and boiling points compared to molecular compounds. Ionic compounds conduct electricity in their molten state and in their aqueous solutions. Molecular compounds are poor conductors of heat and electricity.

Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature.
982165
Ionic compounds are hard and brittle. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not.

In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water. Ionic compounds exist in stable crystalline structures. Therefore, they have higher melting and boiling points compared to covalent compounds.

Solid ionic compounds are poor conductors of electricity. The strong bonds between their oppositely charged ions lock them into place in the crystal. Therefore, the charged particles cannot move freely and carry electric current, which is a flow of charge.

Although solid ionic compounds do not conduct electricity because there are no free mobile ions or electrons, ionic compounds dissolved in water make an electrically conductive solution. ... Therefore, they have higher melting and boiling points compared to covalent compounds.

Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move. Ionic compounds are conductors of electricity when molten or in solution, and insulators when solid.

Ionic compounds typically have much higher melting points than molecular compounds. ... To melt a molecular substance, you need to break these weak intermolecular forces between neutral molecules, which is why ionic compounds generally have much higher melting points than molecular compounds.

In Binary Ionic Compounds and Their Properties we point out that when an ionic compound dissolves in water, the positive and negative ions originally present in the crystal lattice persist in solution. ... Hence the solution conducts an electrical current.

Explaining melting points It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. But some are higher than others. The greater the charge on the ions, the stronger the forces holding them together.

Electricity is carried through ions. In the solid state, due to rigid structure of the compounds, ions cannot flow. Since, ions are unable to flow, no electric current is carried through it.

Explaining melting points It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points.

In short, ionic compounds conduct electricity in water because they separate into charged ions, which are then attracted to the oppositely charged electrode.

Ionic compounds have an equal number of positive and negative ions arranged in the three-dimensional lattice due to which they have high melting points. The strong force of attraction between oppositely charged ions means that ionic compounds have high melting and boiling points.

Explanation: Ionic species are essentially non-molecular with NO molecular boundaries. Given the fact that there are no discrete molecules and strong electrostatic interaction between ions it takes a lot of energy to disrupt the interaction, and this manifests in high melting and boiling points.
