Hi John,
nice hobby you have!

In principle you can convert every oxide into the sulphate, but if it comes to the real world things are not so easy anymore.

The problem a normal person will have with this "conversion" is that you have oxygen in the air. If you do a reaction, you have to heat it in almost every case. But if you heat it and there is oxygen in the atmosphere, you will always get the oxides - and in this special case you will also get molecules of SO2 or something similar.

What you need will certainly be vacuum or an atmosphere with an inert gas (nitrogen or so, something that doesn't react so easily), and probably you don't have the stuff for reactions under inert gases at home (just an assumption), so I think you have to invest that money and buy the sulphates...

But what is the actual case, what do you want to convert? Maybe there is another solution, a little bit easier. Just mail me, you find the address in the header.

Bye, Andreas
