Final answer:
An electrolyte is a compound that conducts an electric current when it is in an aqueous solution or melted. Covalent electrolytes are polar covalent compounds that also conduct electricity when dissolved. Nonelectrolytes do not conduct electricity when dissolved.
Step-by-step explanation:
An electrolyte is a compound that conducts an electric current when it is in an aqueous solution or melted. All ionic compounds are electrolytes. When ionic compounds dissolve, they break apart into ions which are then able to conduct a current. Covalent electrolytes are polar covalent compounds that also conduct electricity when dissolved. Nonelectrolytes do not conduct electricity when dissolved.
In the provided list:
- a. CH3CH₂CH₂OH - covalent electrolyte
- b. Ca(CH3CO2)2 - ionic electrolyte
- c. I₂ - nonelectrolyte
- d. KOH - ionic electrolyte.
