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 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.
Can Potassium change colors?
Potassium itself does not change colors. However, potassium compounds can exhibit different colors depending on their chemical structure and the presence of other elements or compounds in the environment. For example, potassium permanganate is a deep purple color when dissolved in water.
What is electrical energy used to produce a chemical change?
Electrical energy can be used to produce a chemical change through a process known as electrolysis. This involves passing an electric current through a substance to stimulate a chemical reaction, breaking down compounds into their constituent elements or forming new compounds. Examples include the electrolysis of water to produce hydrogen and oxygen gases.
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 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.

Do the physical properties of water change when a compound is dissolved in water?
Yes, the physical properties of water can change when a compound is dissolved in it. For example, the boiling and freezing points of water can be altered, its density may change, and its ability to conduct electricity may be affected depending on the compound dissolved.
How does the electrical conductivity of ionic compounds change when they are melted or dissolve in water?
