Looks like I made quite a few 'educated' guesses that came out right.
it is A, because it has iodine, sure it could be B, except it said "UNAMBIGUOUSLY identify" and carbonate ions also precipitates with calcium (i.e limestone) and sodium (i.e sodium carbonate as seen in the solvay process).Yep this was a really screwed up multiple choice...
And what did every1 get for question 14,
i done the calculation and got A, but thats not what most ppl got....
Also Question 8 would be B would it not?
CO3^2- makes a percipitate with pb^2+
But most ppl got A.. hmm
