What substance conducts electricity in the liquid state but is a poor conductor in the solid state?
In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.
Which substance is a conductor of electricity in the liquid phase but not in the solid phase?
Explanation: Salts when they are added to water can split into their corresponding ions which will serve as shuttles to electrons and therefore, the solution will be conductive.
Which substance will conduct electricity in both the solid phase in the liquid phase?
5) Which substance will conduct electricity in both the solid phase and the liquid phase? 7) Which of the following solid substances contains positive ions immersed in a sea of mobile electrons?
|Substance A||Substance B|
|Solubility in Water||nearly insoluble||soluble|
|Hardness||soft, waxy crystals||hard crystals|
What conducts electricity in solid and liquid state?
Ionics solids are held together by the electrostatic attraction between oppositely charged ions. … When the solid is melted to a liquid, however, the ions are free to migrate. Therefore, ionic liquids are good conductors of electric current. A conductor is a substance capable of transmitting electricity and/or heat.
What types of substances conduct electricity and why?
- Solid ionic compounds don’t conduct electricity. …
- Solutions of ionic compounds and molten ionic compounds can conduct electricity because the ions are free to move around. …
- Metals conduct electricity because the delocalized bonding allows the electrons to move from one place to another.
Does NaCl conduct electricity as a liquid?
Features of Molten Salts
For example, solid sodium chloride (NaCl, or table salt) does not conduct electricity; it is an insulator. … Molten salts conduct electricity the same way they do when they are dissolved in water; some of the salt molecules are dissociated into ions, which allows the ions to conduct electricity.
Which substance conducts electricity in both solid and molten state?
Sodium’s sea of delocalized electrons among the unipositive ions present in the structure is what gives it its conductivity. These delocalized electrons are present in both a solid and molten state, therefore sodium can conduct electricity in both states.
What type of substances did not conduct electricity when solid?
Ionic substances will not conduct electricity as solids. This is due to the fact that ions are not free to move in a solid as they are arranged in an ionic lattice. When an ionic substance is dissolved in solution or molten the ionic lattice is broken down allowing the ions to move freely and so conduction occurs.
Can a gaseous substance conduct electricity in the liquid state?
Yes , Gases do conduct electricity, as all materials do. However, they conduct electricity so poorly that we consider them insulators.
Which types of substances can conduct electricity as solids?
There are two types of substances that are good conductors or electricity. Metals conduct in the solid phase because they contain electrons that are mobile, or free to move around. When a copper wire is used in an electrical circuit it has electrons moving through it whenever the switch is closed.
