waec chemistry practical.

weac practical is among the hardest practical in WAEC, this practical alone contains the 40% of your WAEC chemistry result.

this practical is to test your knowledge of chemistry, on the practical examination, you will be giving some unknown salt solution and they will expect you to conduct an experiment, find out the name, volume and mass of the salt giving to you.

the examination is a tough one for students who showed less interest in learning chemistry during school lectures but it is very simple for brilliant students.

all the questions you see on WAEC chemistry practical must be under the qualitative and quantities analysis.

all science students that are trying to write WAEC should focus on learning how to solve WAEC chemistry practical questions.

here I will be teaching you the solutions for solving WAEC chemistry practical during the examination, what to do if you have low knowledge of chemistry.

in order to solve this practical examination, you need a higher knowledge of chemistry, this example above is called titration.

here is the procedure to follow when solving WAEC chemistry practical questions.

check the instructions given to you in the questions.

put the required amount of salt solution they asked you to put in the appropriate instruments.

titrate and write down your results.

some material used on the practical examination day and precautions in using some of them

weighting balance

chemical balance



filter paper

retort stand


white tile

standard volumetric flask

conical flask.

precautions in using pipette, burette and conical flask.

PIPETTE precautions for using pipette on the examination Hall.

1) rinse the pipette with the solution it should be used to measure i.e base

2) avoid air bubbles in the pipette.

3) make sure that the mark to be read is at the level with your eyes.

4) do not blow the last drop on the pipette.

precautions for using the burette on the examination Hall.

1) rinse the burette with the acid or allow it to dry after rinsing with distilled water.

2) make sure that the burette jet is filled.

3) avoid air bubbles in the burette just like you did on the pipette.

4) take your burette reading with your eyes at the same level as the meniscus to avoid error due to parallax.

5) make sure that the burette is not leaking to avoid any damages on the examination Hall.

6) remove the funnel before taking your reading.

7) avoid inconsistent burette reading.

precautions for using the conical flask on the examination Hall.

1) do not rinse it with any of the solution used in the practical but rinse it with a distilled water.

2) wash down with distilled water any drop of the solution that stick by side of the conical flask during the practical.

how can I learn WAEC practical.

here are the main thing to do if you wish to learn WAEC practical even if you don’t have a chemistry practical teacher.

get a chemistry practical text book, the text book is going to put you through in chemistry, for serious science students, chemistry practical text book is not too cost to purchase.

read volumetric and qualitative analysis: as I said before, the questions must come from volumetric and qualitative analysis, there are numerous topics in chemistry that requires practical like electrolysis, organic chemistry and other but the items required in order to conduct a successful practical in those topics are not cheaply available.

study all the laboratory instruments, their names their functions, check the instruments above, that’s what you will use on the examination practical day.

make use of past question paper, weac is repeating past questions especially chemistry practical, they know that you are aware but still they repeat it REASON They don’t want you to fail, they want you to Master the topic and be ready for your question before the exam day.

ask your tutor question if you’re having problem in understanding any practical topic.

example of WAEC chemistry practical question

let’s now look at how WAEC chemistry practical questions is being set.

the questions in the practical examination are seventy percent from chemistry topic ” volumetric and qualitative analysis”

it always contains three questions in which you are expected to answer all of them.

here are one example of how a WAEC chemistry practical examination is being set and a solution to tackle it.


determine the concentration of hydrochloric acid using standard solution.


hydrochloric acid, standard sodium hydroxide solution, 50cm3 burette, 25 cm3 pipette, methyl orange indicator.


fill the burette with hydrochloric acid and adjust it’s level to the zero mark, pipette 25cm3 of the base into a conical flask and add two drops of the indicator, Note the volume of acid that neutralize the base, tabulate your results and solve the additional questions.
