Answer:
Electrolytes are chemicals that break into ions (ionize) when they are dissolved in water. The positively-charged ions are called cations, while the negatively charged ions are called anions.
Strong electrolytes completely ionize in water. This means 100% of the dissolved chemical breaks into cations and anions.
Weak electrolytes partially ionize in water. Pretty much any dissociation into ions between 0% and 100% makes a chemical a weak electrolyte, but in practice, around 1% to 10% of a weak electrolyte breaks into ions.
If a substance doesn’t ionize in water at all, it’s a nonelectrolyte.
Explanation:
The substance that serves as a good electrolyte in the list is the substance labelled Y.
An electrolyte is a solution that conducts electricity by the movement of ions in the solution. The high concentration of ions in the electrolyte implies that it has a good conductivity
Hence, the substance that serves as a good electrolyte in the list is the substance labelled Y.
