are you talking about Edexcel Unit 3A - it was alright except for the titration. I couldn't see the end point! Why couldn't they just use phenolphthalein?!?

What indicator did you have to use then? Methyl orange?

Hi PEEPS

Chem practicals, can be strange, especially assessed practicals. I've done all mine edexcel ones spread during the year, some of my answers were totally different to everyone elses. I was like omg! Turns out my answers were perfect, normally all my exps mess up. Tecaher was shocked! Look on the bright side of things. Normally I mess around, but you have to be serious once in a while. GCSE was so fun, not the exam but generally the practicals you could do woteva, as long you got good results in the end. School rep n all.

My next exam is on Thurs Psyc, so no point worryin bout it. Its a case of testing memory rather than intelligence but there u go.

GOOD LUCK TO WHOEVA'S GOT EXAMS

Hi! I had the Edexcel practical too.

I got 15.7 cm^3 for titration and that is the correct answer ( i asked my teacher later).

Also the thermochemistry question went okay. The salt was the last one with no hydrogen as the ratio was (1:3).

I did the OCR pratical which was actually quite easy. It was a water of crytstalisation question, and some tests to determine what solution Z was. It turned out to be calcium hydroxide solution :-)

Edexcel, chem practical today, anyone here remember what you get for the formula E solid? i got NH4BR but someone got NH4Cl. And the test with NACO3, so do you put for formula for the ppt? And the planning exercise, do you weigh the ppt? by crystallisation i guess, #finger crossed# Plz anyone share answers with me.

i got 14.45cm3... how many marks do you think i'll lose for this if the supervisor's titre was around 15cm3???

i don't have any of the past marking schemes, could someone who has them tell me how the marks are given. ie: how many marks i'd get if my value was 0.6cm3 different..

i found the OCR one surprisingly easy esp as our mock a couple of wees ago was a water of crystalisation one. i got Z as lime water tho... that the same thing i cat remember? got 7 moles of water aswell. wat bout u?
so relieved the first of it is over!

It will depend on the titration and exactly how easy the endpoint was to see - and what other errors were involved.

What was the titration?

how was the chemistry practicals???
