1. Metals and Acids
23/2/15
Starter: Prediction: What do you think will happen when metals are placed in acid. Explain your answer
Success criteria-
Record observations and evidence systematically.
Describe patterns and trends in results.
Describe the test for hydrogen.
Write word equations for reactions.
Metals neutralise Acids to form a salt and Hydrogen

2. Practical Activity EXPERIMENT-
Add a metal to acid and collect any gas that comes off.
Test the gas.
Write what you observe
You will conduct a test for HYDROGEN gas – H2

3. To know how metals react with acids.
Observations in acid
Squeaky pop test
Do all metals react the same?
What gas is produced?
How do you test for this gas?
Which metal is the most reactive?
Which metal is the least reactive?
What new products have you made?

4. What has been made during the reaction?
Acid
Name of salt
Hydrochloric
Chloride
Sulphuric
Sulfate
Nitric
Nitrate
Why –ide or –ate?
Acid
Formula
Hydrochloric
HCl
Sulphuric
H2SO₄
Nitric
HNO₃
What is different about
hydrochloric but the same
about nitric and sulfuric?

5. What has been made during the reaction?
Metal + acid -> salt + hydrogen
Magnesium + hydrochloric -> magnesium + hydrogen
acid chloride
The name ‘chloric’ becomes chloride and gets added to the metal to become a salt

6. Activity 3
Patterns in the salts
Acid
Second reactant
Name of salt
hydrochloric
iron
iron chloride
Zinc
Lead
nitric
magnesium
Sulphuric
calcium
sulfuric
copper carbonate
copper sulfate
sodium carbonate
zinc carbonate
Complete the table to show the name of the salt that will form when these substances react.
Acid
Name of salt
Hydrochloric
Chloride
Sulfuric
Sulfate
Nitric
Nitrate
