solution question

[Scafalon40]

if you mix manganese sulphate and zinc nitrate in a solution, will you get the same ions in solution if, instead, you use manganese nitrate and zinc sulphate?

 

[farhan143]

you will get manganese nitrate and zinc sulfate if u mix manganese sulfate and zinc nitrate...
and manganese sulfate and zinc nitrate if u mix manganese nitrate and zinc sulfate

 

[Scafalon40]

you will get manganese nitrate and zinc sulfate if u mix manganese sulfate and zinc nitrate...
and manganese sulfate and zinc nitrate if u mix manganese nitrate and zinc sulfate

So is that a yes?

 

[farhan143]

YES!!

 

[Scafalon40]

YES!!

How do you know this?
Any references?
Thanks anyway, though.

 

[farhan143]

no references just a trick question....
the question actually giving you the answer by not giving you...
i wud say this question was a brain teaser....

actually it's quite original.
See nowadays me and a friend are doing P3 past papers in our college's chemistry lab
i like to prepare most of the chemicals myself (don't really trust the lab attendants to get them right!) except for dangerous and corrosive reagents like NaOH etc
the other day i needed to prepare a solution for Q2 salt analysis
it needed manganese sulphate and zinc nitrate
but the lab was out of zinc nitrate
so i was just wondering that since its a solution, won't manganese nitrate and zinc sulphate do the trick
