how sure are u about the P31, why is it important to revise may june 2006
From a topic from princesszahra:
"p31
chem is abt salt analysis and energetics ( with graph)
and in salt analysis in 31 f8 is aldehyde and f9 is ketone"
I've also heard from other topics that there will be no titration, and will be needed to distinguish between aldehydes and ketones. I've been told to revise the tests for aldehydes, ketones, and all types of alcohols (primary, secondary, and terciary). You don't need to know all the tests by heart, they will show you how to do it. You only need to know which test is for which compounds, and the observations for a positive or negative result.
As for energetics, you need to know [ E=mc(delta)T x M/y ] and what the letters stand for, and the usual [ C= n/v ] and [ n = m/Mr ], and I think you'll be fine.
I'm having the exam in 2 hours, so i'll which GOOD LUCK to all of you.
