Lesson Title:
Today we are learning about
How can we use chemical tests to identify unknown ionic compounds?
Remember to check for PROGRESSFocus on Knowledge, Skills and Understanding
Success Criteria:
You will show your learning by...
Flame tests can be used to identify some metal ions (cations). Lithium, sodium, potassium, calcium and copper compounds produce distinctive colours in flame tests: ? lithium compounds result in a crimson flame ? sodium compounds result in a yellow flame ? potassium compounds result in a lilac flame ? calcium compounds result in an orange-red flame ? copper compounds result in a green flame.
If a sample containing a mixture of ions is used some flame colours can be masked
Carbonates react with dilute acids to form carbon dioxide gas. Carbon dioxide can be identified with limewater.
Students should be able to identify species from the results of the tests in 4.8.3.1 to 4.8.3.5.
Halide ions in solution produce precipitates with silver nitrate solution in the presence of dilute nitric acid. Silver chloride is white, silver bromide is cream and silver iodide is yellow.
Flame colours of other metal ions are not required knowledge.
Think about how you can match the needs of ALL students
Keywords:
Halide
: A compound containing a group 7 element.
(1)
Dilute
: A solution containing a relatively small quantity of solute as compared with the amount of solvent.
(1)
Ion
: An atom that has either gained or lost electrons.

AFL/Key Questions:
What are the different colours produced by some metal ions (cations)?
lithium compounds result in a crimson flame ? sodium compounds result in a yellow flame ? potassium compounds result in a lilac flame ? calcium compounds result in an orange-red flame ? copper compounds result in a green flame.
When are some flame colours masked?
If a sample containing a mixture of ions
How do carbonates react with dilute acids?
Carbonates react with dilute acids to form carbon dioxide gas. Carbon dioxide can be identified with limewater.
What do Halide ions produce when they react with silver nitrate solution?
Halide ions in solution produce precipitates with silver nitrate solution in the presence of dilute nitric acid. Silver chloride is white, silver bromide is cream and silver iodide is yellow.
