WAEC GCE Chemistry Practical Questions and Answers 2023/2024 | Alternative to Practical

WAEC GCE Chemistry Practical 2023. Many WAEC GCE candidates find it difficult to answer the WAEC GCE Alternative to Practical Chemistry correctly due to not understanding the questions. I will show you the best way to answer the 2023 WAEC GCE Chemistry Practical questions and get a good grade in your Chemistry examination.

It is pertinent you understand the WAEC GCE Chemistry Practical making scheme before attempting any questions so as to present your answers in such a way that it will look attractive to the examiner to earn you big marks.

Bear in mind that every single procedure is awarded marks. So, ensure you do not skip any step while reporting and presenting your practical results.

The Chemistry Practical question paper will consist of two sections and general Chemistry questions namely:

1. Quantitative Analysis
2. Qualitative Analysis

These involve titration and test of ions. You will be expected to carry out an experiment and report your inference and observation. What you will see will not be far from the WAEC Chemistry Specimen given to your school.

Note: Your titration endpoint will be given to you by your Chemistry teacher. It is not the same for every school but within a range.

Do not use the endpoint here. It may vary from your center endpoint but you can follow the calculation procedures.

Practice Questions

The questions below are strictly for practice, not the 2023 Chemistry expo.

All your burette readings (initials and final), as well as the size of your pipette, must be recorded but no account of experimented procedure is required. All calculations must be done in your booklet.

1. A is O.200 moldm³ of HCI. C is a solution containing 14/3_g of Na₂CO₃. x H₂O in 500 cm³ of solution. (a) Put A into the burette and titrate it against 20.0 cm³ or 25.0 cm³ portions of C using methyl orange as indicator. Repeat the titration to obtain Consistent titre values. Tabulate your results and calculate the average volume of A used. The equation for the reaction is: Na₂CO₃ x H₂O + 2HCL_(aq) → 2NaCI_(aq) + CO2_(g) + (x+1) H₂O_(I).

(b) From your results and the information provided. Calculate the: (i) concentration of C in moldm^-3; (ii) concentration of C in gdm^-3; (iii) molar mass of Na₂CO₃, xH₂O; (iv) the value of x in Na₂CO₃ xH2O. [H = 1.0; C=12.0; O = 16.0; Na =23.0]

Credit will be given for strict adherence to the instruction, for observations precisely recorded and for accurate inferences. All tests, observations and influences must be clearly entered in the booklet in ink at the same time they are made.
