HOW WAS CHEMISTY PRACTICAL?

[BlackVelvet]

So, how was it going? Sorry I've been away for a while due to the crazy spamming to my inbox :lol:

Anyway, keep me updated about the situation here. Thanks.

1. How did the paper go? Time management problem?
2. Any difficulties?

Im doing okay on the 2nd question paper 33. The first one suppose to be okay but I got mixed up and confuse at the beginning.. Most of my friend have time management problem. But I think I do okay probably get C or B.. My calculation difference with the real one is about 60%..

the real problem for me will be time management..

For me it went good Alhamdulillah
I got percentage difference with the real one 9.06% so I think it is ok, but can't say. I may loose some marks here and there in the 1st question around 2 or 3 marks for maybe too high values or too low values.
The salt analysis also went good. I couldn't get the limewater to turn milky but I identified correctly by seeing for bubbles
The cation salt analysis was easy!! So much for knowing cobalt xD!

Inshaallah I can get around 35 out of 40.

yo guys how was p31??

 

[Babuzar]

It was good. At first i accidentally took volume 50cm for experiment 1 and and 100cm3 for experiment 2. I thought that was the error, but then realized at the last moment. "Adjusted" the temp change, and got percentage difference of 0.3% ONLY!. But time was up and i couldn't complete the errors bit. Question two was easy, however i messed up at the end, just wrote Mg+2 instead of Mn+2.

[Carry]

sum say cobalt...how can it be identified...can sumone plz describe the test...
