Why is SO2 incorrect reagent to be used for the formation of BaSO4? It is soluble in water....

 

[Serenity]

GUYS PLEASE REPLY.....

 

[tasnim007]

i think kc is supposed to be 2.25
it goes right with the math
and is not the gas supposed to be CO2

 

[Newbie]

Bilal you shouldn't have apologized in the first place ....

I m warning both of you !! Otherwise I will ask Moderator to take action !!
@ Serenity plz continue !! No one should go out of topic again !! nor discuss the fight between filza and Bilal !!

 

[Serenity]

no.....CO2 is correct for the formation of BACO3....but in the other part they asked about an aqueous reagent used for the formation of BASO4.....so for that I am asking why is SO2 not a correct reagaent?.....

 

[Newbie]

Paper was tough ...

I wrote 3 chiral centres . I don't know whether its wrong or right .

All those people who are saying A will be at 50 ..... what nonsense .... I know that every body comes out after giving their paper . Oh mera to anth gaya ... Oh mein to cha gaya .... let the result come , then you'll stop flying .

 

[armaghanaqib]

hahahah nice lines Newbie!!!...btw it had 2 chiral centres........

 

[armaghanaqib]

@ serenity ...i dont think so2 is the correct reagent....bt cant really justify it

 

[Jokerxxx]

can i ask? Equilibrium not affected by catalyst ma?y must subtract de 0.005 mole oh hcl catalyst? Reply asap

 

[Newbie]

Yes jokerxxx ... I also thought that how equilibrium is affected by catalyst .

 

[Jokerxxx]

so y all ppl also subtract the 0.005 mole of HCl leh??is tis a trap??haha

 

[Serenity]

@ armaghanaqib.....thanks but i wish you had some reason to prove me that SO2 is incorrect reagent....because i wrote SO2, whereas my sister wrote NA2SO4......

 

[armaghanaqib]

@jokerxxx....HCl was catalyst in only the first reaction.....it acted as areactant with NaOH in the second reaction...

 

[armaghanaqib]

@ serenity...im not sure of the answer nw bt ill post the reason here tomorrow....btw ure sisters answer is correct
