Question

which of the following is classified incorrectly based upon the description provided?
○ strong electrolyte — exists as ions in solution
○ nonelectrolyte — exists as molecules in solution
○ weak electrolyte — exists as molecules in solution, with few ions present
○ all are classified correctly.
○ none are classified correctly.

Explanation:

• Strong electrolytes fully dissociate into ions in solution, so their description is correct.
• Nonelectrolytes do not dissociate, existing only as molecules in solution, so their description is correct.
• Weak electrolytes partially dissociate, meaning they exist as a mixture of molecules and a small amount of ions in solution, so their description is correct.

Since all classifications match the behavior of each electrolyte type, none are incorrect.

Answer:

All are classified correctly.
