Question

Acids, Bases, and Salts quick check

Answer 1

Sure! Here’s a quick overview of acids, bases, and salts:

### Acids
- **Definition**: Substances that release hydrogen ions (H⁺) in solution.
- **Properties**:
- Sour taste
- Corrosive
- Turn blue litmus paper red
- React with metals to produce hydrogen gas
- **Examples**:
- Hydrochloric acid (HCl)
- Sulfuric acid (H₂SO₄)
- Acetic acid (CH₃COOH)

### Bases
- **Definition**: Substances that release hydroxide ions (OH⁻) in solution or accept hydrogen ions.
- **Properties**:
- Bitter taste
- Slippery feel
- Turn red litmus paper blue
- Can react with acids to form salts and water (neutralization)
- **Examples**:
- Sodium hydroxide (NaOH)
- Potassium hydroxide (KOH)
- Calcium carbonate (CaCO₃)

### Salts
- **Definition**: Ionic compounds formed from the neutralization reaction of an acid and a base.
- **Properties**:
- Generally crystalline solids
- Can conduct electricity when dissolved in water (electrolytes)
- **Formation**:
- Acid + Base → Salt + Water
- Example: HCl + NaOH → NaCl (table salt) + H₂O

### Key Concepts
- **pH Scale**: Ranges from 0 to 14, measuring the acidity or basicity of a solution.
- pH < 7: Acidic
- pH = 7: Neutral
- pH > 7: Basic
- **Neutralization Reaction**: A reaction between an acid and a base that produces a salt and water.
