Waec 2013 Free Chemistry Practicals: Questions to Expect!
The Questions to always expect on Chemistry is always TITRATION,
i Guess by now you should know how
to TABULATE your readings & at the same time, Manipulate your Readings to get Your end point.

N.B: Please note that your teacher will
give you an end point you will work on.

Practice How To Manipulate Your Table.
Always remember, this is one of the utmost key.
If your school’s end point is 23.30cm^3, you shouldn’t exceed or – 0.20.

That is, it is a thing of Plus or Minus 0.20.

If Your school’s end point is 23.30, please note that it is either your Answer is 21.30,
24.30,
25.30,
22.30.

Likewise, please note that Your Volume of Pipette Used Should be noted on your answer sheet.
Indicator Used should also be noted.

However, to show how good you are,
you can also decide to tell the
examiner the solution in Burette and also the solution in Pipette.
This must be done before the Table.

Make sure that you do not forget to put the Units of all what you have calculated.

Also note that Any unit which is omitted, attracts a worrisome deduction of 1/2 (Half mark).
