NECO Chemistry Practical Specimen for 2017/2018 June/July Neco Examination officially Out.
Official 2017 Neco Specimen for Neco Chemistry Practical – Those writing Chemistry in this year’s Neco examination is advised to read the specimen provided by Neco themselves here.
All the chemistry practical questions will be coming from the specimen provided by them. There a lot of specimens out there but the ability to determine the actual one from Neco is the beginning of your success.
All the specimens I drop here are direct from Neco Office. Science students do take do take about 4 major Practical’s during SSCE examination. I will give you the specimens of all the science subjects which include:
Neco Chemistry Practical Specimen, Neco 2017 Physics Practical Specimen, Neco Biology Specimen 2017 and Agric Specimen for Neco practical.
When you study all of them and know them very well, you will be sure to smash chemistry and make good grades when the result eventually comes out.
Subsequently, I will show you how to get Neco practical specimen for all subjects. I am sure you will like it because it will cover a lot.
Now, let’s see what is contained in the Neco Practical Specimen which was officially released by Neco body for her 2017/2018 June/July Examination.
Official 2017 Neco Specimen for Neco Chemistry Practical
Below are expected Neco Specimen for chemistry practical 2017. This first appeared on Neco past question papers and will be good for your consumption.
Measured Dilute sodium hydroxide solution
Measured Dilute ammonia solution
Some quantity of Dilute hydrochloric acid
A rubber filled with Distilled water
Blue and and Red litmus paper for practical
New Fehlings solution (I & II)
A glass filled with concentrated tetraoxosulphate (vi) solution (H2SO4)
Recently prepared iron (II) tetraoxosulphate (VI) solution (Fe2SO4), burette (60cm 3), pipette (30cm3 or 35cm3), filtration apparatus, methyl orange, boiling tube, test tubes, SALTS: CuO,ZnSO4,Na2CO3
QUESTION 1 (Past Question)
This is how the question may come out on the exam day: In addition to the fittings and reagents normally contained in a chemistry laboratory, the following apparatus and materials will be required by each candidate
1 burette of 60cm3 capacity
1 pipette, either 30cm3 or 35cm3. All candidates at one centre must use pipettes of the same volume. These should be clean and free from grease
Regular Apparatus For Titration in Chemistry
This is a complete list of usual/regular apparatus and reagents for qualitative work including the following with all reagents appropriately labelled to avoid mistake.
Four test tubes
Wash bottle containing distilled/deionized water
Dilute sodium hydroxide solution
Barium chloride solution
Dilute trioxonitrate (V) acid
Dilute hydrochloric acid
Silver trioxonitrate (V) solution
Dilute tetraoxosulphate (VI) acid
Two boiling tubes
QUESTION 2 – NECO CHEMISTRY QUESTION SAMPLE
According to National Examination Council (NECO), each candidate should be supplied with the following, where ‘n’ is the candidate’s serial number.
150cm3 of ethanedioic acid (H2C204) solution in a corked flask or bottled labelled ‘An’. These should all be the same containing 4.50g of H2C204 per dm3 of solution.
150cm3 of potassium tetraoxomanganate (VII) solution in a corked flask or bottle labelled ‘Bn’. These should all be the same containing 3.16g of KMnO4 per dm3 of solution.
One spatulaful of a uniform mixture of NaCl and ZnCO3 in a specimen bottle labelled ‘Cn’. The components of the mixture should be in the ratio 1:1 by mass.
