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.

Why do ionic compounds conduct electricity when dissolved in water but most covalent compounds do not?
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 compounds conduct electric current when they are melted or dissolved think about what's happening to electrons in an ionic bond?
ionic compounds that are dissolved in water or melted will conduct electricity; molecular compounds do not conduct electricity in either case. ... atoms that lose electrons become positively charged ions,and atoms that gain electrons become negatively charged ions. The oppositely charged particles attract each other.
When an ionic compound dissolves in water the solution conducts electricity?
If the force between the ions and the water molecules is strong enough to break the bonds between the ions, the compound dissolves. The ions dissociate and disperse in solution, each ringed by water molecules to prevent reattachment. The ionic solution turns into an electrolyte, meaning it can conduct electricity.
What happens when ionic compounds are dissolved?
When you immerse an ionic compound in water, the ions are attracted to the water molecules, each of which carries a polar charge. ... When this happens, the ions dissociate and disperse in solution, each surrounded by water molecules to prevent it from recombining.
Why do ionic compounds not conduct electricity when solid?
Ionic bonds are the electrostatic attraction between positive and negative ions. Ionic solids exist as networks/lattices of oppositely charged ions. Ionic compounds do not conduct electricity in solid state as the ions are not free to move.
Why do ionic compounds dissolve in water?
Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.
What happens when ionic compounds dissolve in water quizlet?
when an ionic compound dissolves in water, the positive ends of the water molecules are attracted to the anions and the negative ends are attracted to the cations.
When an ionic compound dissolves in water chegg?
When an ionic compound dissolves in water, the individual ions first leave the crystal lattice and then each ion becomes surrounded by a cluster of polar water molecules.
Why do some ionic compounds not dissolve in water?
But some ionic compounds do not get dissolved in water. This is because the ionic forces in those molecules are very high, which creates high lattice energy. Due to high lattice energy, the hydration energy decreases that makes those compounds insoluble in water. ... Hence, all ionic compounds are not soluble in water.
Why do covalent compounds conduct electricity?
This is due to the availability of free electrons or ions in their molten state. Thus, polar covalent compounds conduct electricity in their molten form.
Do covalent compounds conduct electricity when dissolved in water?
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 are ionic compounds brittle?
Ionic compounds are generally hard, but brittle. Why? It takes a large amount of mechanical force, such as striking a crystal with a hammer, to force one layer of ions to shift relative to its neighbor. ... The repulsive forces between like-charged ions cause the crystal to shatter.
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 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 better electrical conductors than molecular compounds?
Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don't dissociate into ions and so don't conduct electricity in solution.
