Distinguishing Salt analysis ....Chemistry 34.

[Irreversible]

plz help anyone!!!!!!! how to distinguish Aluminium ions from Lead ions... Both have similiar observations with NaOH and NH3?????

addition of HCL, it will form a precipitate with lead(II) ions but not with aluminum ions

Do you know any information about tomorrow's exam?

Do you know any information about tomorrow's exam?

Not Yet... and thanxs for the help.. do you knw wat came in 33??? i mean error thingies??? if it came then it will be must in our paper too.

Nopp, what are we supposed to study for the exam anyways? Any specific points?

and can u also tell me wat to do if my results come colourless for succesive salt analysis test???
and in titration how do i knw which indicator to add????

They'll probably provide you with an indicator such as phenolphthalein

In 33, there was salt analysis, hydration/crystallization and titration.
so enthalpy might be coming and we know salt analysis and titrations are must.... Just revise how to draw graph, gradient triangle and record observations in tables... and lets hope paper is super easy and we can do our best

Hopefully it will be easy!

Dude the best way to prepare for prac is to just go through 5 past papers that would be enough i think just remember draw tables neatly and gradient triangle must be of mediun size for accurate result.... Salt analysis try to understand wats happening in the test rather just observing your results, u might get observations marks but u won't be able to identify the ions...

pracs have so many variants that is not possible to do five years lets hope for the best fingers crossed

enthalpy aint coming titration and salt analysis are coming

 

[Irreversible]

enthalpy aint coming titration and salt analysis are coming

u sure????

 

[Dania_Yz]

You sure?? And thank youuu best of luck

yea well thats all i know

 

[blah4023]

yea well thats all i know

I second that. I am pretty confident that enthalpy isn't coming
I really hope it's just titration and salt analysis with minimum calculation.
Hydration is easy marks though

lol now my another friend just texted saying that there are three questions in total... so i dont kw what whose right he or that other one
