It will not be straight forward - read carefully.
for eg: container A contains 2mol/dm3 of H2So4.
when they say, 50cm3 from container A, make sure it's A, double check, if not, later it's 50cm3 from container B.
(essential) in calculations for titration. All info up there.
Remember to label properly. Furthermore, after you label your answers, remember UNITS.
if not for eg, you write 5.00
5.00 what?
5.00 monkeys or cm3?
Originally posted by Darkiish:if its the experiment on tiltrations, what is the possible answers for precaution and error made.
the acidic co2 from the air react with alkali. (previous page). error.
Precaution - read at eye level to prevent inaccurate volumes of chemicals measured.
do note: Use scientific terms.
I have told you what i know.
I may leave out somethings.
One last thing would be - Handphones, electronic devices, PDAs, pages, all in your bag. Outside the room. Pls switch off and put to silent.
and no communication. you will be sitted accordingly to your index. check the arrangement.
next, would be, if your lab is small, you guys will be next to each other - do not communicate still. Or look at other's script.
Note: Learn calculations - Moles.
Pg 298 (chapter 18 is important). read up.
All the best.
my school have not yet covered the topic on mole. so the question given will not be given in moles? units is a must and calculations must will rounded off to their precisions.
have not covered =/
Then your Spa should not have titration. Titration and calculations are inter connected. So highest bet would be QA. test for cations and anions.
I said, should not, but not meaning, will not.
Post back tml on the topic.- but remember, not the answers.
ok thx
