1. Which of the listed substances is an electrolyte? 1. Potassium hydroxide solution 2. Alcohol solution 3. Sugar

1. Review each substance to determine if it is an electrolyte, which means it can conduct electricity when dissolved in water.

1) Potassium hydroxide solution - Yes, potassium hydroxide is an ionic compound that dissociates into K+ and OH- ions when dissolved in water, making it an electrolyte.

2) Alcohol solution - No, alcohol does not dissociate into ions when dissolved in water, so it is not an electrolyte.

3) Sugar crystals - No, sugar (sucrose) is a molecular compound that does not dissociate into ions in water, making it a non-electrolyte.

4) Sugar syrup - No, just like sugar crystals, sugar syrup does not contain ions and does not conduct electricity when dissolved in water, so it is a non-electrolyte.

Based on these observations, the substance that is an electrolyte from the given options is Potassium hydroxide solution.

2. Now, let"s analyze the given substances to determine which one is a non-electrolyte, meaning it does not conduct electricity when dissolved in water.

1) Sulfuric acid solution - No, sulfuric acid is a strong acid that dissociates completely into H+ and SO4^2- ions in water, making it an electrolyte.

2) Sodium hydroxide solution - No, sodium hydroxide is a strong base that dissociates completely into Na+ and OH- ions in water, making it an electrolyte.

3) Table salt solution - No, table salt (sodium chloride) is an ionic compound that dissociates into Na+ and Cl- ions in water, making it an electrolyte.

4) Glucose solution - Yes, glucose is a molecular compound that does not dissociate into ions in water and does not conduct electricity, making it a non-electrolyte.

Therefore, the substance that is a non-electrolyte from the given options is Glucose solution.

3. Determine which option represents two weak electrolytes.

1) H2SO4 and NaCl - No, both sulfuric acid (H2SO4) and sodium chloride (NaCl) are strong electrolytes, fully dissociating into ions in water.

2) HF and H2CO3 - Yes, both hydrofluoric acid (HF) and carbonic acid (H2CO3) are weak electrolytes. They only partially dissociate into ions in water.

3) NaOH and Na2SO4 - No, both sodium hydroxide (NaOH) and sodium sulfate (Na2SO4) are strong electrolytes, fully dissociating into ions in water.

4) KOH and H2S - No, both potassium hydroxide (KOH) and hydrogen sulfide (H2S) are strong electrolytes, fully dissociating into ions in water.

Therefore, the option that represents two weak electrolytes is 2) HF and H2CO3.

4. Identify the substances that form the same anions in an aqueous solution.

1) FeCl3 and Fe(OH)3 - No, these two compounds form different anions. FeCl3 forms Cl- ions, while Fe(OH)3 forms OH- ions.

2) BaSO4 and Na2SO4 - Yes, both barium sulfate (BaSO4) and sodium sulfate (Na2SO4) form the same sulfate (SO4^2-) anions in water.

3) Ba(OH)2 and Cu(OH)2 - No, these two compounds form different anions. Ba(OH)2 forms OH- ions, while Cu(OH)2 forms Cu^2+ and OH- ions.

4) AgNO3 and HNO3 - No, these two compounds form different anions. AgNO3 forms NO3- ions, while HNO3 forms H+ and NO3- ions.

Therefore, the substances that form the same anions in an aqueous solution are 2) BaSO4 and Na2SO4.
