Question

which substance can be classified as a nonelectrolyte?○ licl○ $\text{kno}_3$○ $\text{h}_2\text{o}_2$○ $\text{mgcl}_2$○ naoh

Explanation:

A nonelectrolyte does not conduct electricity in aqueous solution because it does not dissociate into ions. Ionic compounds (like LiCl, KNO₃, MgCl₂, NaOH) are strong electrolytes that fully dissociate into ions. Hydrogen peroxide (H₂O₂) is a covalent compound that does not dissociate into ions in water, so it is a nonelectrolyte.

Answer:

○ H₂O₂
