Step 2:: Understanding Electrolyte Classification
Electrolytes are substances that conduct electricity when dissolved in water. They are classified based on their ability to dissociate into ions: - Strong electrolytes: Completely dissociate into ions - Weak electrolytes: Partially dissociate into ions - Nonelectrolytes: Do not dissociate into ions
Step 3:: Sodium Permanganate (NaMnO_{4})
- When dissolved in water, it completely dissociates into $$Na^{+}$$ and $$MnO_{4}^{-}$$ ions
- Sodium permanganate is an ionic compound - Classification: Strong electrolyte
Step 4:: Acetic Acid (CH_{3}COOH)
- Partially dissociates in water into $$CH_{3}COO^{-}$$ and $$H^{+}$$ ions
- Acetic acid is a weak organic acid - Classification: Weak electrolyte
Step 5:: Methanol (CH_{3}OH)
- Methanol is an alcohol - Does not dissociate into ions when dissolved in water - Classification: Nonelectrolyte
Step 6:: Calcium Acetate (Ca(CH_{3}COO)_{2})
- Completely dissociates in water into $$Ca^{2+}$$ and $$CH_{3}COO^{-}$$ ions
- Calcium acetate is an ionic compound - Classification: Strong electrolyte
Final Answer
(a) Sodium permanganate: Strong electrolyte (b) Acetic acid: Weak electrolyte (c) Methanol: Nonelectrolyte (d) Calcium acetate: Strong electrolyte
