explain why aqueous solution of ionic compounds are able to 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.

a) Ionic compounds b) Metals c) Water. Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.

Ionic compounds dissolve in water because the water molecules hydrate the ions.

Hydrogen and hydroxide ions. Acidic and alkaline solutions can conduct electricity because they have ions that are free to carry charge. Look at the formulae of these acids. ... They all contain OH - ions.

Ionic compounds typically have high melting and boiling points, and are hard and brittle. As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized.

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.

Pure water is not a good conductor of electricity. ... Because the electrical current is transported by the ions in solution, the conductivity increases as the concentration of ions increases. Thus conductivity increases as water dissolved ionic species.

All ionic compounds are electrolytes. When ionic compounds dissolve, they break apart into ions which are then able to conduct a current ( conductivity ). Even insoluble ionic compounds such as CaCO 3 are electrolytes because they can conduct a current in the molten (melted) state.

Some of the properties of ionic solids are high melting point, low vapor pressure, brittleness and the inability to conduct electricity. Ionic compounds can be readily dissolved by polar molecules like water.

Ionic Compounds in Water When ionic compounds dissolve in water, they break apart into the ions that make them up through a process called dissociation. When placed in water, the ions are attracted to the water molecules, each of which carries a polar charge.

Answer and Explanation: When AgNO3 is placed in water, Ag+ and NO3 - ions form. When ionic compounds dissolve in water, they'll begin to conduct electricity because they form...

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. But all that changes when ionic compounds dissolve in water.

Explanation: To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. They do this by hydrating the ions. ... When you place an ionic substance in water, the water molecules attract the positive and negative ions from the crystal.

These can then conduct electricity. We can say that salts like KCl dissociate in water easily, while polar covalent compounds like HCl dissociate with some difficulty. ... But their solutions do not conduct electricity. This is because although weakly polar, they do not separate into ions in water.

Ionic compounds are hard and brittle. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not.

ConductivityEdit Acids and bases in aqueous solutions will conduct electricity because they contain dissolved ions. Therefore, acids and bases are electrolytes. ... Weak acids and bases will be weak electrolytes.

Substances like sodium chloride which strongly conduct electricity in aqueous solution are called strong electrolytes. ... Substances like sucrose which do not conduct electricity in aqueous solution are called non-electrolytes.
