 If you are participating in the upcoming 2022 WAEC Chemistry exams and you are probably wondering how you can make sure you get an "A" in your WAEC Chemistry exams without involving in exam malpractice, well, this post 2022 WAEC Chemistry specimen is for you.

Well, number one hint I will give you which will enable you succeed in the upcoming 2022 WAEC Chemistry exams is to follow the WAEC syllabus when deciding what topics to study for the exam. Your textbook is great, however, some of the topics covered in the textbook are not necessarily going to come out in the exam. Some topics are just for your information and you will not be tested on them. If you cannot get your hands on a copy of the syllabus at your school, try and find out how you can get a copy from friends in other schools and otherwise.

RECOMMENDED

WAEC RECOMMENDED TEXTBOOKS

Also endeavor to have a complete lesson notes on Chemistry from SS1 to SS3. If you are not sure you have complete lesson notes, you can always pair up with a friend in class to compare lesson notes and make sure they are complete. If your lesson notes are not complete, try and photocopy from classmates who have complete notes. In the alternative, you should please subscribe to this site for updates.  

STATUS OF THIS WORK:Highly confidential for the students who were to take the exam.This work is just a reference point to those students who are inquisitive about the sources of practical specimens and should not be used for any other purpose other than waec exam, the concentrations of the acid and bases are standard for both waec and neco and may be used in secondary school laboratories.This post should not be used in a way that will post damage to the waec body. 

PREPARATION: Prior to the exam date, the practical specimens are always listed on paper and sent to various secondary schools intending to participate in the waec examination and is always made highly confidential.This is to avoid the information from reaching the students. 

Now let's take a look at the practical exam teacher's report information from waec office sent to subject teachers of various schools prior to the exam date in 2022!

1. Great care should be taken to ensure that the information given in items 2 and 3belowdoes not reach the candidates either directly or indirectly before the examination.

2. In addition to the fittings and reagents normally contained in a chemistry laboratory, the following apparatus and materials will be required by each candidate.

a)One burette of 50cm³capacity.

b)One pipette, either 20cm³ or 25cm³.

All candidates at one center must use pipettes of the same volume.

These should be clean and free from grease.

c)The usual apparatus for titration.

d)The usual apparatus and reagents for qualitative work.

Including the following with all reagents appropriately labelled.

i.Dilute sodium hydroxide solution.

ii.Dilute hydrochloric acid.

iii.Dilute trioxonitrate (v) acid

iv.Silver trioxonitrate (v) solution.

v.Barium chloride solution.

vi.Aqueous ammonia.

vii.Lime water.

viii.Red and blue litmus paper.

ix.Dilute tetraoxosulphate (VI) acid.

e) Spatula

f) Filtration apparatus.

g) One beaker

h) One boiling tube

i) Four test tubes.

j) Starch solution as indicator.

k) Mathematical table/calculator

l) Wash bottle containing distilled/deionized water.

3.Each candidate should be supplied with the following Where n is the candidate’s serial number.

a. (a) 150cm³ of sodium trioxosulphate (VI) solution in a corked flask or bottle, Labelled “An”.

These should all be the same containing 6.0g of Na2S2O3 per dm³ of solution.

b.150cm³ of iodine in potassium iodide solution in a corked flask or bottle labelled “Bn”.

These should all be the same containing 2.5g of I2 and 1.67g of KI per dm³ of solution.

c.One spatula full of a uniform mixture of NaCl and CuCO3 in a specimen bottle labelled “Cn”.

4.The components of the mixture should be in the ratio 1:2 by mass

 In all cases, more materials maybe issued if required.

5.The actual concentrations of A and B must be stated on the Supervisor’s Report form.

The candidates will assume that the concentrations are exactly as stated in the question paper.

Those were the instructions from the teachers report form for waec practical chemistry specimen 2019.It should act as a guide for students intending to write 2020 waec examination and also to some chemistry teachers and laboratory attendance interested in creating a standard waec solutions and bench reagents in their laboratories.
