Question

Identify each of the following compounds as: (a) a nonelectrolyte: ethanolamine (C₂H₅ONH₂), potassium fluoride (KF), ammonium nitrate (NH₄NO₃), isopropanol (C₃H₇OH), barium hydroxide [Ba(OH)₂], lactose (C₁₂H₂₂O₁₁) (b) a weak electrolyte: ethanolamine (C₂H₅ONH₂), potassium fluoride (KF), ammonium nitrate (NH₄NO₃), isopropanol (C₃H₇OH), barium hydroxide [Ba(OH)₂], lactose (C₁₂H₂₂O₁₁) (c) a strong electrolyte: ethanolamine (C₂H₅ONH₂), potassium fluoride (KF), ammonium nitrate (NH₄NO₃), isopropanol (C₃H₇OH), barium hydroxide [Ba(OH)₂], lactose (C₁₂H₂₂O₁₁)

Answer 1

The compounds ethanolamine, isopropanol, and lactose are nonelectrolytes. Potassium fluoride is a weak electrolyte. Ammonium nitrate and barium hydroxide are strong electrolytes.

Step-by-step explanation:

a. Nonelectrolyte: The compounds ethanolamine (C₂H₅ONH₂), isopropanol (C₃H₇OH), and lactose (C₁₂H₂₂O₁₁) are nonelectrolytes because they do not dissociate into ions when dissolved in water. Weak electrolyte: The compound potassium fluoride (KF) is a weak electrolyte because it partially dissociates into ions in water. Strong electrolyte: The compounds ammonium nitrate (NH₄NO₃) and barium hydroxide [Ba(OH)₂] are strong electrolytes because they completely dissociate into ions in water.
