Why do ionic compounds conducts electricity in molten state whereas not conducts electricity in the fused state?

Ionic compounds conduct electricity in solution because they are made up of electrically charged ions but covalent compounds are made up of electrically neutral molecules so they do not conduct electricity. Hence ionic compounds conducts electricity in molten state and does not conducts electricity in the fused state.

Why are ionic compounds soluble in water?

Most ionic compounds are soluble in water. Polar water molecules have a strong attraction for charged ions and the charged ions become solvated as they dissociate into the water and ionic compounds are soluble in water.

Why are ionic solids conducting in molten state and not in the solid-state?

Ionic Solids Conduct Electricity In Molten State But Not In Solids State. This is because, in ionic compounds, electricity is conducted by ions. In contrast, ions are held together by strong electrostatic forces in a solid-state and are not free to move about within the solid.

Why can ionic compounds conduct electricity when in molten state or when in water while covalent compounds Cannot conduct electricity in both phrases?

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. In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

Why do ionic crystals conduct electric current in the liquid phase?

In liquid ionic crystals, the ions are no longer held together tightly. The ions are to move past one another and hence ionic solids in their liquid phase conduct electricity.

Why are ionic compounds insoluble in nonpolar liquids?

Polar solvents like water decrease the electrostatic forces of attraction, resulting in free ions in aqueous solution. Non-polar solvents like kerosene, benzene are not capable of dissolving ionic solids since they can not decrease the forces of attraction between the ions.

What is conducts electricity when in solution but not in solid phase?

Ionic solids conduct electricity in molten state but not in solid state.

Why do certain compounds conduct electricity?

2) Solutions of ionic compounds and molten ionic compounds can conduct electricity because the ions are free to move around. When an ionic compound dissolves in solution, the ions of the molecule dissociate. These ions are electrochemically charged in solution and can conduct electricity, making them electrolytes.

Why do ionic crystals conduct electric current in the liquid phase or when dissolved in water but do not conduct electric current in the solid phase quizlet?

Do ionic compounds conduct electricity in molten state?

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. This is thoroughly answered here.

Why do ionic compounds move towards each other when heated?

Ionic compounds are made up of ions. The opposite ions are strongly attracted to each other in solid state. The ions do not move but vibrate. If they are heated the vibration of the ions increases and gradually they become free from each other. So in molten state the free ions move towards their respective electrodes.

How is ionic current produced in a solid?

Ionic current is through physical movement of ions. In solid state, ions in salts are not free to move physically and hence they do not carry current. In liquid state/ molten state / in solutions the ions are loose and free to move in fluid. Therefore they can move freely towards terminals / plates of opposite polarity.

Can solid ionic lattices conduct electricity?

However when solid ionic lattices are heated or dissolved in water the ions are free to move and can therefore conduct electricity as they carry the electrical charges.
