Ethanol is slightly alkalineph meter not possible as both are neutral so cant distinguish but for ethanol and ethanoic acid ph meter is possible!
pH around 8-8.5

no bro im damn sure about it!Ethanol is slightly alkaline
pH around 8-8.5
anhydrous cobalt chloride is also possible !I'd rather you add dehydrated copper salts.
With water, they change from white to blue.
Ethanol, no change
Lol good luck !! Waisay Hamza Iqbal ki shakal bohut buri ho gayi thi jab paper mila !! LOLJO smjhna hay Smj loo
Inshallah Ho jai gaa
lol everyone knows transitions metals are colored but i doubted if i needed to write cobalt or only transition metalThis is from the examiner's report. "Only the most able candidates scored well on this question. Nitrate ions were sometimes
successfully identified but the identity of solution K as a transition metal compound was rare. The
presence of ammonium ions and copper was often given even though the solution was pink to start
with."
The pink solution suggests that copper is NOT present, Copper salt solutions are BLUE.
Hope I'm right. Anyone one is free to correct any errors![]()
No we don't !!do any of youll want to see the march series paper ,chemistry paper 6
This allows a user in a remote location to control a device.The device would have an embedded micro processor.Wht is embeddedd web technology
I want it plz...do any of youll want to see the march series paper ,chemistry paper 6
Yup!is my diagram correct? If not please tell me how to draw
(And ignore my drawing i knw it's really bad)
K thanks dudeYup!
yeh plz?? Plz i really need it plz do upload???do any of youll want to see the march series paper ,chemistry paper 6
THANKU!!!!!!!There are two scenarios for this:-
1) Check this paper first(MJ2011 QP61 Q4 e(iii)):- https://drive.google.com/folderview...sp=drive_web&tid=0BzumkDfi9230ajBJb1BVUl8xODg
So in this case the student is pouring solution(for which concentration is being checked) of potassium manganate(VII) from the beaker. Thus, the lesser the volume required for the colour to change, the more concentrated it is.
2)https://drive.google.com/folderview...drive_web&tid=0BzumkDfi9230ajBJb1BVUl8xODg(MJ 2008 QP6 Q4 e(iii))
So in this case the solution for which concentration is being checked is not poured, the known volume is already in the flask. Thus, whatever is being poured, in this case potassium manganate(VII), has to be in larger volume.
So basically you just have to look if the solution checked for concentration(i.e. A and B) has a known volume or not. If it does not, then the one with the smaller difference is more concentrated. If it does have a known volume, then one with larger difference is more concentrated.
Good luck for your exams
