Classify these compounds as strong electrolytes, weak electrolytes, or nonelectrolytes. Strong electrolyte Weak electrolyte Nonelectrolyte
AnswerA strong electrolyte completely dissociates in water whereas a weak electrolyte is partially dissociated in water. A non-electrolyte does not dissociates in water and thus, do not form ions. Since, HNO3 is strong acid therefore, it is a strong electrolyte. K3PO4 is a strong base since it is formed from a strong base KOH and weak acid H3PO4 therefore, it is a strong electrolyte. HOCl is a weak acid therefore, it is a weak electrolyte.
Hence, HNO3 and K3PO4 are strong electrolytes and HOCl is a weak electrolyte.
