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.
Can conduct electricity when they are dissolved in water?
An electrolyte is any salt or ionizable molecule that, when dissolved in solution, will give that solution the ability to conduct electricity. This is because when a salt dissolves, its dissociated ions can move freely in solution, allowing a charge to flow.
Which compound will conduct electricity when it is dissolved in water?
Polar covalent bonds form when two atoms have similar yet not identical electronegativity values (e.g., H2O, HCl, HI). These compounds do dissolve in water and do conduct electricity. For example, hydrochloric acid (HCl) and hydroiodic acid (HI) are strong acids that completely dissociate into their ions in water.
Why do Electrovalent compounds conduct electricity?
Electrovalent compounds are good conductors of electricity in the fused or aqueous state because electrostatic forces of attraction between ions in the solid state are very strong and these forces weaken in the fused state or in the solution state. Hence, ions become mobile.
Which compound will conduct electricity when it is dissolved in water quizlet?
– Materials that dissolve in water to form a solution that will conduct electricity are called electrolytes.
Why do ionic compounds conduct electricity well when they are dissolved in water?
Conduction of electricity
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 are conductors of electricity when molten or in solution, and insulators when solid.
Why do most 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.
Why do 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 water and ionic compounds are soluble in water.
