Which compound forms an electrolyte solution when dissolved in water? \( \begin{array}{l}\mathrm{LiCl} \\ \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \text { (glucose) } \\ \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH} \\ \mathrm{Br}_{2}\end{array} \)

When lithium chloride (\(\mathrm{LiCl}\)) is dissolved in water, it dissociates into lithium ions (\(\mathrm{Li}^+\)) and chloride ions (\(\mathrm{Cl}^-\)), forming an electrolyte solution. This means it can conduct electricity due to the movement of these charged particles, making it a common choice in battery technology and colligative properties experiments! On the other hand, compounds like glucose and ethanol don't produce ions when dissolved in water, so they won't form electrolytes. Using them as solvent additives can create interesting effects, but they won’t help with electrical conductivity like \(\mathrm{LiCl}\) does!
