E)No precipitate will form.

Accepted Answer

Zn²⁺ and SO₄^2- are both soluble, so no precipitate will form.

Question 14

The distinguishing characteristic of all electrolyte solutions is that they
A)contain molecules.
B)conduct electricity.
C)react with other solutions.
D)always contain acids.
E)conduct heat.

Accepted Answer

Electrolyte solutions are able to conduct electricity due to the presence of ions. This is a distinguishing characteristic that sets them apart from non-electrolyte solutions, which do not conduct electricity.

Question 16

Which of the following compounds is a nonelectrolyte? A)NaOH B)HNO₃ C)C₂H₆O(ethanol) D)KF E)CH₃COOH (acetic acid)

Accepted Answer

Ethanol (C2H5OH) is a covalent compound, meaning it does not dissociate into ions in solution and thus does not conduct electricity. Therefore, it is a nonelectrolyte. NaOH (A) and KF (D) are both strong electrolytes, as they completely dissociate in solution into ions and conduct electricity. Acetic acid (E) is a weak electrolyte, as it only partially dissociates into ions in solution and conducts electricity to a limited extent. The formula given in choice B (HNO₃) is not a known compound.

Question 17

Which of the following compounds is a weak electrolyte? A)HNO₃ B)NaNO₃ C)HNO₂ D)NaNO₂ E)NaOH

Accepted Answer

A and B are both soluble salts and will fully dissociate in water, making them strong electrolytes. E is a strong base and will also completely dissociate in water, making it a strong electrolyte. D contains a strong base (NaOH) and a weak acid (HNO2), but since NaOH is a strong electrolyte it will completely dissociate and make the entire compound a strong electrolyte. 
C contains a weak acid (HNO2) which will only partially ionize in water, making it a weak electrolyte.

Question 18

Based on the solubility rules, which one of the following compounds should be insoluble in water? A)Na₂SO₄ B)BaSO₄ C)CuSO₄ D)MgSO₄ E)Rb₂SO₄
