It looks like you're trying to classify some substances based on their acid-base characteristics. Here's how those substances fit into the categories of strong acids, weak acids, strong bases, and weak bases:
Strong Acids:
- Hydriodic acid (HI)
Weak Acids:
- Acetic acid (CH₃COOH)
- Hydrofluoric acid (HF)
Strong Bases:
- Lithium hydroxide (LiOH)
Weak Bases:
- Ammonia (NH₃)
Water is considered neutral and can act as both an acid and a base (amphoteric), but it is typically not classified strictly as an acid or base in this context.
So the classification would be:
- Strong Acid: Hydriodic acid
- Weak Acids: Acetic acid, Hydrofluoric acid
- Strong Base: Lithium hydroxide
- Weak Base: Ammonia
Feel free to ask if you need more information about these substances!
