Why do ionic compound have high elctrical conductivity in the molten state and in water solution?

Ionic compounds are the compounds with dissociate into cations and anions when dissolved in solution. For example regular table salt (NaCl) is a ionic compound when dissolved in water dissociate into Na+ and Cl- , such a solution then can conduct electricity. Pure water with no impurities (no dissolved ions) is a modest insulater. Ionic compounds are combination of a metal and a non-metal.

Is the element mercury polar or non-polar?
The element Mercury is considered to be non polar. It is not a compound but a molten metal. Mercury atoms are bonded to each other with metallic bonds.
How is plastic dyed?
Before the plastic is molded dyes are added to the molten plastic.
Why KCl or KF is added in the electrolysis of molten NaCl?
To decrease melting point of NaCl
What is melted rock?
Melted rock is that hasn't surfaced is "Magma".If the melted rock already has surfaced, it is called "Lava".
What is the Molten liquid rock inside Earth's mantle called .?
Molten rock in any of Earth's layers is called magma. The mantle is actually composed of solid, but very hot and plastic-like rock.
How does the elctrical conductivity of ionic compounds change when theey are melted or dissolved in water Why is this so?
Electrical conductivity rises dramatically, and this is due to mobile ions that move in solution or the molten salt under the influence of an electrical field. These mobile ions carry the current.
What form can an ionic compound conduct energy?
either in solution or in molten / fused state
A compound that does not conduct an electric current in aqueous soltion or in molten state?
A compound that does not conduct an electric current in aqueous solution or in molten state is a covalently bonded compound. It could also be called a "non-ionogen".
How do you increase the conductivity of molten copper?
Magnitize it
Is molten gold a solution?
A molten metal is not a solution, it is a liquid.
What another way of saying electrolyte?
n 1. a solution or molten substance that conducts electricity2. a chemical compound that dissociates in solution into ions, any of the ions themselves
Is a molten compound a liquid?
Yes. "Molten" means the compound has melted into the liquid state. Anything that heat has melted into a liquid can be described as molten.
Why does sodium chloride conduct when molten or in solution?
It conducts due to the presence of free ions in molten and solution state.
Is salt solution is a good conductor of electricity?
Salt in solution improves conductivity but it does not make a conductor as good as a metal. Deionized water has an electrical conductivity of 5,5 * 10-6 [S*m-1] but Seawater (3,5% salt in solution) has a conductivity of 4,8 [S*m-1] compared to Sliver with a conductivity of 6,3 * 107 [S*m-1] (the best known at room temperature)
What are three characteristics property of ionic compound?
Three characteristics of ionic compounds are listed here. 1) They are solid at room temperature. 2) As solids they do not conduct electricity (however, when molten they do) 3) They have low thermal conductivity.
Why electrical conductivity is a suitable test for ionic compounds?
Ionic compounds only have high conductivity in a molten state. Because they are composed largely of a tightly-bonded lattice of cations and anions, electric charge cannot flow through the lattice because of the lack of freedom possessed by any negatively charged particles. When the compound is in a liquid state, the electrostatic bonds between the cations and anions are weakened, allowing the negatively charged ions to move freely and, because of this, it easily conducts a charge. Hope that's been some use :)
Do ionic compound's or covalent molecole's conduct electicity?
Ionic compounds conduct electricity in aqueous solution or molten state. In aq. soln. or molten state, ionic compounds dissociate to release respective ions. These ions, being electrically charged, conduct electricity.
