What must we know a given ionic salt to be able to predict whether is is a good or poor conductor, w/o testing its conductivity?

What is its dissociation constant?

I assume you are looking to predict the solution of the salt.

Very few ionic crystals are good conductors unless dissolved.

Yes

I assume you are looking to predict the solution of the salt.

yes Bob

Students at the University of North Texas and the University of Washington built a car propelled by compressed nitrogen gas. The gas was obtained by boiling liquid nitrogen stored in a 200.0 L tank. What volume of N2 is released at 0.910 atm of pressure and 25 degrees C from a tank full of liquid N2 (d= 0.808 g/mL)?

To predict whether a given ionic salt is a good or poor conductor without testing its conductivity, you need to consider several factors:

1. Nature of ions: Ionic salts are composed of positively charged cations and negatively charged anions. The mobility of these ions plays a crucial role in determining the conductive properties. Ions that are highly mobile tend to make the salt a better conductor.

2. Ionic charge: The magnitude of the charge on the ions affects their mobility. Higher charge ions generally have greater mobility, resulting in better conductivity.

3. Ionic size: The size of the ions also influences their ability to move. Smaller ions can more easily move through the crystal lattice of the salt, enhancing conductivity.

4. Crystal structure: The arrangement of ions in the crystal lattice affects the conductivity. Some crystal structures allow for better ion movement, leading to higher conductivity.

5. Solubility: If the salt is highly soluble in a solvent, it indicates the presence of dissociated ions. Dissociation of ions in solution is a prerequisite for ionic conductivity.

By considering these factors, you can make an educated prediction about the conductivity of a given ionic salt. However, it is important to note that physical properties and conductivity can vary depending on temperature, pressure, and other external factors. Experimental testing is the most reliable way to determine the conductivity of a salt.
