How do electrical conductivity of ionic compounds change when they are melted or dissolved in water?
When ionic compounds are placed in water, they cause the water to conduct electricity. Normally, water doesn't conduct electricity well at all. However, when salts dissolve in water, they break up into their constituent cations and anions and it is the presence of these ions that allows it to conduct electricity. Because salts conduct electricity when dissolved in water, they are referred to as electrolytes. In the same way, pure salts conduct electricity only when they are melted. As a solid, the anions and cations in an ionic compound are locked in place and unable to move electrical charge. However, when the ionic compound is melted, these ions are free to move around and conduct charge. Electrolytes are compounds that conduct electricity when dissolved in water. Many ionic compounds are considered to be electrolytes. However some ionic compounds don't dissolve in water. As a result, they do not share this property.

Why does the electrical conductivity of ionic compounds change when they are melted or dissolved in water?
The electrical conductivity of ionic compounds increases when they are melted or dissolved in water because the ions are free to move and carry electric charge. In the solid state, the ions are fixed in place and cannot conduct electricity. When melted or dissolved, the ions are able to move freely and carry electric current.
Why does the electrical counductivity of ionic compounds change when they are dissolved in water?
When ionic compounds dissolve in water, they dissociate into their constituent ions, which are free to move and carry electric charge. This movement of ions allows for the flow of electric current, increasing the electrical conductivity of the solution compared to the solid compound.
Why does the electrical conductivity of ionic compounds change when they are dissolved in water?
Electric current is the flow of charged particles. When ionic crystals disolve in water, the bonds between ions are broken. As a result, the ions are free to move about, and the solution conducts current. Likewise, when an ionic compound melts, the ions are able to move freely, and the liquid conducts current. In contrast, ionic compounds in solid form do not conduct current well. The ions in the solid crystal are tightly bound to each other and cannot move from place to place. If charged particles cannot move, there is no current.
How does the conductivity of a solution change in relation to its concentration?
The conductivity of a solution generally increases as its concentration increases. This is because a higher concentration means there are more ions present in the solution, which allows for better electrical conductivity.
Why does the temperature change when ionic compounds dissolved in water?
When ionic compounds dissolve in water, the temperature can change due to the enthalpy change of the solution forming. This can be influenced by factors such as the lattice energy of the ionic compound and the hydration energy of the dissolved ions. Additionally, if the dissolution process is exothermic, it can release heat and increase the temperature of the solution.
How does electric conductivity of ionic compounds change when they are melted or dissolved in water?
Melting or dissolving ionic compounds increases the electrical conductivity. This is because there are free mobile charged ions that can move in the electric field and conduct current.

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.

Is electrical conductivity a chemical change?
No, electrical conductivity is a physical property that depends on the ability of a material to carry an electric current. It is not a chemical change because the chemical composition of the substance remains the same.
How conductivity effects power?
Conductivty is an electrical property of conducting materials. Silver has the higest conductivity, then copper then aluminimum. Conductivity does not really change with electrical wiring so the power will not be directly affected.
What change occurs when AgCl is doped with CdCl2?
The electrical conductivity is modified.
What factor should change in electrical conductivity of metals and non metals?
In metals, electrical conductivity increases with higher number of free electrons, which can be influenced by factors like temperature and impurities. In non-metals, electrical conductivity is generally lower due to lack of free electrons, but can increase with doping or introduction of impurities.
Is Copper conducts electricity physical or chemical?
Electrical conductivity is not a change but is a physical property.
What is the change in conductivity as the concentration of the NaCl solution was increased by the addition of NaCl drops?
The electrical conductivity of the solution will be higher if the concentration of NaCl increase.
