hahaha I do know this. It's the stuff we use to mess around with the lab's chemicals when the teacher is busy ..
Just one final thing (really sorry to disturb today), in oct/nov 01 in question 13, why is it not A (P only)
lol same here, our students act like 9 year old, take the syringes and start spraying water at
each other.
Are u sure the anw is A.
Q)which Group 7 element is produced at which anode.
1 solution has Molten lead(II) bromide. Bromine gas produced at P.
2 solution concentrated hydrochloric acid. Chlorine is supposed to be formed at R.
I think it should be B (P and R)
Or chloride ions dont move in concentrated solutions
