Answer 2

Oil is not an electrolyte. (option d)

• Electrolytes: These are substances that get dissolved into ions (positive and negatively charged) and conduct electric current on dissociation.
• Non-electrolytes: They do not get dissolved into ions, therefore they do not conduct electric current.
• The salt solution, copper sulfate solution, and lemon juice are electrolytes as they undergo dissociation into ions and conduct electricity Whereas oil does not dissociate into ions.
• Therefore oil(option d)  cannot be used as an electrolyte.
