ph was 12.5 right?What was the indicator ? that range in alkaline condition right ? other 3 was suitable for more acidic ones.

it was trickier than most people here think it was
I can bet my life most people got the Electrode Potential Wrong
Seemed simple I know
Wasnt exactly what it seemed.
I could go on and on about the various small stuff in the paper which people are presuming to be easy and werent exactly straightforward but paper discussion is not allowed.
We are done with paper 41
We can start discussion
i got that tooph was 12.5 right?
I was really confused abt this.. i chose -0.13electrode potential was -0.19v right?
Shifting to left won't make it more positive?oh i thought since concentration of PbCl2 was lesser than 1 moldm-3, the equilibrium will shift to the left, making Ep more negative.
. I got +2242. I hope examiners would give me 2 out 3.it is always negative... I got -2242KJmol-1
Honestly, not quite suremy pH was coming as 11. How many marks will I lose. and can Sn and Hcl be used for reduction.
Can KI be used as a reducing agent in Sn reaction?Honestly, not quite sure
depends on where you made the mistake
ecf might get you marks
as for reducing agent
agreed Sn + HCl is a reducing agent
but im not someone you should be asking
I was as surprised as you are and checked LiAlH4 from the net
