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. However, sodium chloride as at the solid state is a neutral compound and will not conduct electricity.
What conducts electricity as a liquid but not a solid?
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 cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Why does liquid iodine not conduct?
Answer: Melting point: Iodine is liquid so it doesn’t have a melting point. Conductor of Eletricity: Iodine does not conduct electricity since each molecule of iodine comprises two iodine atoms joined by a covalent bond that cannot be excited sufficiently to transfer electrical energy.
Which object is the best conductor of electricity?
“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
How do you know if a substance conducts electricity?
The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. … The higher the concentration of ions, the greater the conductivity.
What are 5 good conductors?
Does sulfur conduct electricity as a liquid?
Sulphur is a non-metal so it does not conduct electricity.
What kind of substance is good to conduct electricity in it’s solid form?
Metals are good electrical conductors in the solid form, and have characteristic luster and malleability. Most metals are solid at room temperature and have melting points that range from below 0°C to over 2000°C. They are not soluble in water or organic solvents.
What type of solids are electrical insulator?
Covalent solids or network solids are very hard with high melting point and are insulators in solid as well as in molten state.
Can conduct electricity in the solid and liquid phase?
Since the ions cannot move, ionic solids are non-conductors of electricity. 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.
