Question

1. what are the properties of acids and bases?

acid properties
base properties

Explanation:

To answer the properties of acids and bases, we recall the common chemical properties:

Acid Properties:

• Taste sour (e.g., vinegar, citrus).
• React with metals (e.g., Zn + HCl → H₂ gas).
• Turn litmus paper red.
• React with carbonates to produce CO₂ (e.g., HCl + Na₂CO₃ → CO₂).
• pH < 7 (in aqueous solution).

Base Properties:

• Taste bitter, feel slippery (e.g., soap, lye).
• Turn litmus paper blue.
• React with acids in neutralization (e.g., NaOH + HCl → H₂O + NaCl).
• pH > 7 (in aqueous solution).
• Some bases (alkalis) dissolve in water; others (e.g., Cu(OH)₂) are insoluble.
