Determine if the ffg are strong, weak, nonelectrolytes:
Sulfuric acid - strong?
Potassium hydroxide - strong?
Carbonic acid - strong?
Propyl amine - weak?
Potassium iodide -weak?
Ethanol - strong ?
Glucose - nonelectrolyte?
am i right?
I don't know what ffg means. If you are look for strong, weak, non-electrolytes, then
3,5,6 are wrong.
To determine if a substance is a strong, weak, or nonelectrolyte, you need to consider its ability to dissociate into ions when dissolved in water.
1. Sulfuric acid (H2SO4): Strong electrolyte. Sulfuric acid is a strong acid that completely dissociates into H+ and SO4²- ions in water. So, it forms a solution that conducts electricity well.
2. Potassium hydroxide (KOH): Strong electrolyte. Potassium hydroxide is a strong base that fully dissociates into K+ and OH- ions in water. Therefore, it also forms a solution that conducts electricity effectively.
3. Carbonic acid (H2CO3): Weak electrolyte. Carbonic acid is a weak acid that only partially dissociates into H+ and HCO3- ions in water. It forms a solution that conducts electricity to a limited extent.
4. Propyl amine (C3H7NH2): Weak electrolyte. Propyl amine acts as a weak base and undergoes partial dissociation into C3H7NH3+ and OH- ions in water. Hence, it forms a weak electrolyte solution.
5. Potassium iodide (KI): Strong electrolyte. Potassium iodide is a strong salt that fully dissociates into K+ and I- ions in water. Consequently, it forms a solution capable of conducting electricity efficiently.
6. Ethanol (C2H5OH): Nonelectrolyte. Ethanol is a molecular compound that does not readily dissociate into ions when dissolved in water. It does not conduct electricity, so it is categorized as a nonelectrolyte.
7. Glucose (C6H12O6): Nonelectrolyte. Glucose is also a molecular compound that does not dissociate into ions when dissolved in water. It does not conduct electricity either and is classified as a nonelectrolyte.
So to summarize, your answers are as follows:
- Sulfuric acid: Strong electrolyte (Correct)
- Potassium hydroxide: Strong electrolyte (Correct)
- Carbonic acid: Weak electrolyte (Correct)
- Propyl amine: Weak electrolyte (Correct)
- Potassium iodide: Strong electrolyte (Correct)
- Ethanol: Nonelectrolyte (Correct)
- Glucose: Nonelectrolyte (Correct)
