Question

How do you know when a salt is a strong electrolyte?

Answer 1

When you learn what makes something a strong electrolyte, and can apply your knowledge of the salt to determine if it qualifies.

That's applied knowledge, one of the most valuable kinds.

Answer 2

You know a salt is a strong electrolyte when it can be broken down into many elements.To do this, you need to look at the chemical formulas.  The more pieces it can be broken down into, the better the electrolyte.

NaCl = Na + Cl

CaCl2 = Na + Cl + Cl

CaCl2 is a stronger electrolyte, because it can be broken down into 3 segments, whereas NaCl can only be broken down into 2.

Hope this helps!
