Step 1:I'll solve this problem step by step, classifying each substance based on its chemical composition:
Step 2:: KOH (Potassium Hydroxide)
- Classification: $$\boxed{\text{Base}}
- Contains hydroxide (OH⁻) ion - Completely dissociates in water
Step 3:: HF (Hydrofluoric Acid)
- Classification: $$\boxed{\text{Acid}}
- Contains hydrogen ion (H⁺) - Proton donor
Step 4:: Ca(OH)₂ (Calcium Hydroxide)
- Classification: $$\boxed{\text{Base}}
- Contains hydroxide (OH⁻) ions - Metal hydroxide that completely dissociates
Step 5:: KI (Potassium Iodide)
- Classification: $$\boxed{\text{Salt}}
- Salt formed from neutralization of HI and KOH - Neither acidic nor basic
Step 6:: NaCl (Sodium Chloride)
- Classification: $$\boxed{\text{Salt}}
- Salt formed from neutralization of HCl and NaOH - Neither acidic nor basic
Step 7:: HCl (Hydrochloric Acid)
- Classification: $$\boxed{\text{Acid}}
- Contains hydrogen ion (H⁺) - Proton donor
Step 8:: HNO₃ (Nitric Acid)
- Classification: $$\boxed{\text{Acid}}
- Contains hydrogen ion (H⁺) - Proton donor Final Classification: - Bases: KOH, Ca(OH)₂ - Acids: HF, HCl, HNO₃ - Salts: KI, NaCl
Final Answer
- Classification: \boxed{\text{Acid}}
