Lesson: Further Tests for Anions Chemistry

Start Practising

In this lesson, we will learn how to identify a selection of aqueous negative ions based on their reactivity and the color and solubility of their salts.

Lesson Plan

Students will be able to

  • describe the test and results for the bicarbonate anion,
  • describe the test and results for the sulfide anion,
  • describe the test and results for the thiosulfate anion,
  • describe the test and results for the nitrite anion,
  • describe the test and results for the phosphate anion,
  • write ionic equations for the tests for bicarbonate, sulfide, thiosulfate, nitrite, and phosphate anions,
  • identify the anion in an unknown solution using the tests above.
