Identifying ions in solution
Narrated lesson · press play
Chemistry detective work: given an unknown salt, which ions are inside it? Learn the standard NIED tests — sodium hydroxide and ammonia for metal cations, silver nitrate and barium nitrate for anions, and the flame test colours — exactly as they appear in the exam.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 8.1):
- Describe tests to identify the cations: aluminium, calcium, ammonium, copper(II), iron(II), iron(III), zinc (using aqueous sodium hydroxide and aqueous ammonia)
- Describe flame tests for Li⁺, Na⁺, K⁺, Ca²⁺, Ba²⁺
- Describe tests to identify the anions: carbonate, chloride, bromide, iodide, nitrate, sulfate
- Draw conclusions from the results of such tests
