Which of the following are electrolytes sugar, no2 bacl2 co ca (oh) 2 feso4 gasoline?

Electrolytes are substances whose solutions or melts are capable of conducting electric current. Electrolytes are substances of a covalent, strongly polar or ionic structure, as well as metals.

Of the listed substances, electrolytes are:

– barium chloride (BaCl2) – decomposes into ions in solution;

– ferrous sulfate (FeSO4) – ionic structure;

– a weak electrolyte is calcium hydroxide (Ca (OH) 2) – although it has an ionic structure, it is poorly soluble in water.

Sugar and gasoline have a molecular structure, the molecules are not polar, they are not electrolytes. NO2, CO – gases, do not conduct electric current.
