Acids and Bases

Question 1

Amphiprotic species

Answer 1

• H20 (Water)
• HSO4 (1-)
• H2PO4 (1-)
• HPO4 (1-)

the negative charges make the amphiprotic as the can loose and donate proton (water is special)

Question 2

Reactions

Answer 2

Neutralisation: When an acid and base react to form salt and water

Metal and Acid: When an acid and metal react to form salt and hydrogen

Metal hydroxide and Acid: When an acid and metal hydroxide react to form salt and water

Metal carbonate and Acid: When an acid and metal carbonate react to form salt, water and carbon dioxide

Combustion: fuel + oxygen = H2O + CO2

Question 3

Common Acids

Answer 3

• Hydrochloric acid (HCL)
• Sulphuric acid (H2SO4)
• Nitric acid (HNO3)
• Ethanioc acid (CH3COOH)
• Carbonic acid (H2CO3)
• Phosphoric acid (H3PO4)

Question 4

Common Bases

Answer 4

• Sodium hydroxide (NaOH)
• Ammonia (NH3)
• Sodium carbonate (NaCO3)
