How was Chemistry Paper 61 May June 2015

[Muaaz Iqbal]

I think no effect will be correct !!

Yea I also Think So

 

[Muaaz Iqbal]

I think no effect will be correct !!

From now maximum I have lost 5 to 6 mark's lol

 

[Mr.Physics]

From now maximum I have lost 5 to 6 mark's lol

which ones ?? I have lost 2 only !! One for the graph and one here LOL

 

[Mr.Physics]

What did you write for non metal electrode and why iron shouldn't be used as an electrode

 

[Muaaz Iqbal]

What did you write for non metal electrode and why iron shouldn't be used as an electrode

Well for non-metal electrode I wrote Carbon,Platinum.

 

[Muaaz Iqbal]

which ones ?? I have lost 2 only !! One for the graph and one here LOL

I have lost 1 in electrode one, 1 mark for the reliability one, 2 mark for the identification of solid , 1 mark in Smell one

 

[Mr.Physics]

Well for non-metal electrode I wrote Carbon,Platinum.

Platinum is a metal LOL

 

[Muaaz Iqbal]

Platinum is a metal LOL

My first option Was Carbon and then Platinum

 

[FAHAD imtiaz]

I've lost one in smell, one in solvent,2 or 1 in Bunsen burner one and 2 or 1 in acid one so total abt 6

 

[FAHAD imtiaz]

Are you sure that its acceptable?
Did you see this somewhere?
Source?Also majority of the answers are bleached litmus.

Majority answer is bleaches but the correct answer is it bleaches it very slowly ! Not like chlorine so we have to wait in order to observe the effect ! No effect is also acceptable according our school's chemistry teacher

 

[FAHAD imtiaz]

I wrote carbon! And in iron one I wrote it is not suitable and not inert inert means un reactive while iron is reactive so we can write it as not inert electrode as it can react!!

My first option Was Carbon and then Platinum

 

[FAHAD imtiaz]

which ones ?? I have lost 2 only !! One for the graph and one here LOL

How u lost mark in graph one? What mistake u did?

 

[FAHAD imtiaz]

Iron is REACTIVE so if used it would react with the electrolyte.

More over inert means un reactive I also wrote iron is not inert electrode ! Meaning it is reactive ! So same ! Kyon dara rahe ho :-/ !

 

[Kiara P.]

Lol :/

Well anyway, I hope they would accept this answer and take it into account it's all up to the examiners right now... !

 

[FAHAD imtiaz]

if they won'so np coz I also wrote that iron is not suitable !

 

[Kiara P.]

if they won'so np coz I also wrote that iron is not suitable !

Haan xD !

 

[Mr.Physics]

Haan xD !

I wrote that iron would get rusted !! Is that correct ??

 

[Kiara P.]

I wrote that iron would get rusted !! Is that correct ??

The solution was barium sulphate right..?
Which if it was barium SULPHATE <------ It's an ACID
And Iron rusts in the presence of ACIDS
.

.
.
So

.
YASSS YOUR ANSWER IS CORRECT ACCORDING TO MY MEASUREMENTS

Nope the electrolyte was lead bromide !! Wondering that you really gave paper 61 lol

 

[Kiara P.]

Oh crap. Great now my memory is cheating over me :c ...
But still lead (II) Bromide is kind of a solution so it must have water or something ( God knows what) so It would rust
so again your answer is correct!

U-uh I guess ...

Lol no no yaar I'm sure it's 62!
Proof to that the first Question had a condenser with label in and out .
