Self Assessment Checklist – Qualitative Analysis

Knowing the learning objectives is the first step in acing Chemistry. Master the essential concepts and apply them to interesting Chemistry questions confidently. Topical syllabus objective checklists are available here for your self-assessment. These checklists are based on Cambridge O-level Syllabus. Conduct self assessment when you revise. Tick against objectives that you can confidently say ‘I Can Do It’. Revise objectives that you are unsure of. Knowing what you need to know builds confidence in tackling questions. 

Work hard. Work smart. All the best.

Self Assessment Checklist - Qualitative Analysis

  I Can Do This!
aDescribe the use of aqueous sodium hydroxide and aqueous ammonia to identify the following aqueous cations: aluminium, ammonium, calcium, copper(II), iron(II), iron(III), lead(II) and zinc (formulae of complex ions are not required).
bDescribe tests to identify the following anions:
b(i)

carbonate (by the addition of dilute acid and subsequent use of limewater)
b(ii)chloride (by reaction of an aqueous solution with nitric acid and aqueous silver nitrate)
b(iii)iodide (by reaction of an aqueous solution with nitric acid and aqueous silver nitrate)
b(iv)nitrate (by reduction with aluminium in aqueous sodium hydroxide to ammonia and subsequent use of moist red litmus paper)
b(v)sulfate (by reaction of an aqueous solution with nitric acid and aqueous barium nitrate)
cDescribe tests to identify the following gases:
c(i)ammonia (using damp red litmus paper)

c(ii)carbon dioxide (using limewater)
c(iii)chlorine (using damp blue litmus paper)
c(iv)hydrogen (using a burning splint)
c(v)
oxygen (using a glowing splint)
c(vi)sulfur dioxide (using acidified potassium manganate(VII)).
(d)Describe tests to confirm the presence of water: using cobalt(II) chloride paper or using anhydrous copper(II) sulfate.
