GT kitny pe hoga ? :/

 

[avenger]

around 20 i guess. what do u say?

hey...just to get some if yr opinion,if my table for question 2,got a wrong expression for the data..n so my values r all wrong..including the graph,anomalies n gradient..will there be any error carried forward???

paper went good.......the paper was lengthy but it was not that hard........it was just time management that caused some problems!!!!

 

[meobunny]

[Resha rimaz]

I put HCl in d burette, but aftr d ppr when we asked d teacher she told co(oh)2 shud b in d buretteDunno why though coz aftr all we wanna determine conc of Ca(oh)2

GT will be 16-18

i was confused during dilution but i used some <dont remember the volume> 2moldm-3 hcl in 250 cm3 gaaduated flask and diluted it!
i was also confused on dropping acid or base form burette? i dropped acid and indicatior phenolpathelin colourless to pink
gradient for no. 2 was 4.8 so i wrote 5
was these correct??? if these are wrong please tell me how much marks am i losing???
PLEASE PLEASE PLEASE

I used universal indicator for the ease of differentiating since i was confused abt the change in colour of phenolphthelin

Q2 was quite easy
Q1 was a bit tricky..and I'm sure il lose around 4 marks on that question...not sure....I used acid in the burette too
Overall it wasn't a bad paper...expecting in 20s
