2.1.2 Formulae, Acids, Bases & Salts

Question 1

What is the

Ionic Equation for Acid + Ammonia

Answer 1

H + + NH3 –> NH4 +

Proton + Ammonia –> Ammonium ion

Question 2

What is the

Ionic Equation for Acid + Metal Carbonate

Answer 2

2H + + CO3 2- –> CO2 + H2O

2 Protons + Carbonate ion –> Carbon Dioxide + Water

Question 3

What is the

Ionic Equation for Acid + Metal Hydroxide

Answer 3

H + + OH - –> H2O

Proton + Hydroxide ion –> Water

Question 4

What is the

Ionic Equation for Acid + Metal Oxide

Answer 4

2H + + O 2- –> H2O

2 Protons + Oxygen ion –> Water

Question 5

What are the

Observations for Acid + Metal

Answer 5

• Bubbles of gas (effervescence)
• Solid dissolves

Effervescence - hydrogen escaping | Solid dissolves - no solid products

Question 6

What are the

Observations for Acid + Ammonia

Answer 6

• No visable observations

Ammonium ions & Ammonia are both aqeous

Question 7

What are the

Observations for Acid + Metal Carbonate

Answer 7

• Bubbles of gas (effervescence)
• Solid dissolves

Effervescence - CO2 escaping | Solid dissolves - no solid products

Question 8

What are the

Observations for Acid + Metal Hydroxide

Answer 8

• No visable observations

H+ & OH- form water

Question 9

What are the

Observations for Acid + Metal Oxide

Answer 9

• Solid Dissolves

Metal forms a salt, oxygen forms water
