What else can I help you with?
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 iodine a good electrical conductor?
No
Is the electrical conductivity of molten metals high or low?
Metals are already good electrical conductors, and melting metals increases their electrical conductivity. All that heat (thermal energy) allows electrons a lot more mobility so they can more effectively contribute to current flow.
Does NaCl conducts electricity?
Not in its normal, solid form but it will when molten or dissolved in water.
What is the electrical conductivity of salt?
Salt (NaCl) is a poor conductor of electricity when it is in solid form because its ions are held in a fixed position. However, when salt is dissolved in water or molten, it dissociates into its constituent ions (Na+ and Cl-) which can conduct electricity due to the movement of charged particles.
What is the conductivity of CuSO4?
Copper (II) sulfate is a poor conductor of electricity in solid state. When dissolved in water, it, like most salts, becomes conductive. One would expect that molten CuSO4 would also conduct electricity.
How do you increase the conductivity of molten copper?
Magnitize it
Can dissolved salt separate into sodium and chloride when it has electrical current running through it?
Sodium Chloride dissolved in water will form sodium but sodium reacts with water to form sodium hydroxide, molten sodium chloride will do it .
Do Ionic compounds have poor or good conductivity?
Ionic compounds have good conductivity when in solution or molten state because the ions are free to move and carry an electric charge. However, in solid form, ionic compounds have poor conductivity because the ions are held in fixed positions and cannot move to carry a charge.
Do ionic solids have high conductivity when solid?
No, ionic solids typically do not have high conductivity when solid because the ions are held in fixed positions and cannot move freely to carry an electric current. Conductivity in ionic solids usually occurs only when they are molten or dissolved in a liquid, where the ions are free to move.
What is the conductivity of AlCl3?
Aluminum chloride, represented by molecular formula AlCl3, is a compound of aluminum and chlorine. An aqueous solution of aluminum chloride conducts electricity fairly well, but this is not currently reliably quantified.
Is salt a conductor?
Sodium chloride is an electrical conductor only in solution or when is melted.
