Acids, Bases, and Salts quick check

1 answer

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.
