Study Notes
Characteristics of Acids
- Acids have a sour taste
- They turn blue litmus to red
- They give positive hydrogen (H+) ions in water solution
Types of Acids
- Strong Acids: HCl (Hydrochloric Acid), H2SO4 (Sulphuric Acid), HNO3 (Nitric Acid)
- Weak Acids: CH3COOH (Acetic acid), Oxalic Acid, Lactic Acid
- Concentrated Acids: have more amount of acid and less amount of water
- Dilute Acids: have more amount of water and less amount of acid
Chemical Properties of Acids
Reaction of Acid with Base
- Acid + Base → Salt + Water
- This reaction is called Neutralization reaction
- Examples: KOH + HCl → KCl + H2O
Reaction of Acid with Metal
- Acid + Metal → Salt + Hydrogen gas
- Example: Mg + 2HCl → MgCl2 + H2
Reaction of Metallic Oxides with Acids
- Metal oxide + Acid → Salt + Water
- Example: CuO + HCl → CuCl2 + H2O
Reaction of Acid with Metal Carbonate and Metal Hydrogen Carbonates
- Acid + Metal carbonate/Metal hydrogen Carbonate → Salt + CO2 + H2O
- When an acid reacts with a metal carbonate (MCO3) or metal hydrogen carbonate (MHCO3), it gives the corresponding salt, carbon dioxide (CO2) gas and water
