If you are participating in the upcoming 2020 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 2019 WAEC Chemistry specimen is for you.
Well, number one hint I will give you which will enable you succeed in the upcoming 2019 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.

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 to 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 2019!
INSTRUCTIONS TO SCHOOLS HIGHLY CONFIDENTIAL
1.Great care should be taken to ensure that the information given below does not reach the students either directly or indirectly before the examination.
2.In addition to the apparatus and reagents expected to be available in secondary school chemistry laboratory;each candidate will require the following:
(1)One burette (50 cm3).
(2)One pipette (20/25 cm3).However ,all candidates in a centre must used pipette of the same volume.
(3)The usual apparatus and reagents for qualitative work including;
(i)Dilute sodium hydroxide solution
(ii)Dilute ammonia solution
(iii)Dilute hydrochloric acid
(iv)Barium chloride solution
(v)Distilled water
(vi)Red and blue litmus paper
(vii)Phenolphthalein
(vi)methyl orange
(vii)One boiling tube
(viii)Five test tubes
(ix)Filtration apparatus
(x)Source of heat
(3)Each candidate should be supplied with the following :An,Bn,Cn.Where 'n' is the candidate serial number.
(a)150cm3 of tetraoxosulphate (VI) acid solution in a bottle labelled "An".
The acid solution which should be the same for all candidates will contain 3.4 cm3 of concentrated tetraoxosulphate (VI) acid per dm3 of solution.
(b)150cm3 of sodium hydroxide solution in a bottle labelled "bn".
The solution which should be the same all candidates will contain 4.0g of sodium hydroxide per dm3 of solution.
(c)One spatula of copper (II) tetraoxosulphate (VI) salt in specimen bottle labelled "cn".
4.In all cases,more materials may be given if required.
5.The actual concentration of A and B must be stated on the subject teacher's report form,while the candidates should make used of the concentrations stated in the question question paper.
6.Please, do not substitute any substance or solution for those specified in these instructions.
ARRANGEMENT AND SERIAL NUMBERS OF CANDIDATES
7.Place for work by candidates in the laboratory should be numbered serially and the candidates allotted these places strictly in order of their examination numbers.
8.The number of every specimen suppiled to each candidate should tally with his/her serial number.If a candidate is absent,his/her serial number must not be allocated to another candidates.
9.If candidates are divided into sets, the serial number should be continued through the sets to ensure no serial number is repeated.
10.Ensure that the candidates record their serial numbers as well as their examination numbers on the front of their answer booklets at the beginning of the examination.
11.Ensure that a completed teacher's report form is enclosed in each envelope of scripts. This report from is provided separately.
12.Carry out the titration required of the candidate in question 1,and record the titre values which should be atleast,one decimal place in the spaces provided for these in the teacher's report form.Verify the titre values before recording them.
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.
