Double displacement reaction
Can Cesium carbonate and Ammonium nitrate be prepared using the double displacement reaction from Cesium nitrate and Ammonium carbonate?
I dont have any chemistry education so i try find this out myself, but all examples and texts i find about the double displacement reaction doesnt
cover Cesium nitrate.
Is it possible to use the double displacement reaction like this?
CsNO3 + AmCO3 -> CsCO3 + AmNO3
If this would work, both CsNO3 and AmNO3 is soluble in water so how would one go about separating them?
Can the double displacement reaction be preformed in other solvents than water?

cesium carbonate is extremely soluble in water, wouldnt work

check how much is Cs2CO3 soluble in H2O
I had to let it to sit over molecular sieves in desiccator for more than 1 month as my compound was slightly wet, this is perhaps the most hygroscopic
carbonate I have ever worked with... I have a little of Rb2CO3 which should be even more soluble in water but I have never opened the vial yet, the
Rb2CO3 is perfectly dry and well bottled... the Cs2CO3 was a cheap buy prior which I was notified that it is slightly wet, so its price was
significantly lowered (cca 70 EUR per 355 grams), otherwise it is quite expensive
NH4NO3 again very soluble in water.
CsNO3 as well (NH4)2CO3 are much less soluble in cold water so your reaction is in opposite direction, from right to left
also NH4HCO3 is not so well soluble in cold water
Is your goal to produce Cs2CO3? Then react it with an acid to produce its other salt?

The goal is CsCO3 and i have some CsNO3.
I was thinking i might be able to make some AmNO3 as a bonus.
I read about turning the CsNO3 into Cesium oxalate and then to Cesium Carbonate by thermal decomposition but it seem about 600°C is needed.
So you recommend reacting the CsNO3 with an acid, say HCl, and get the Cs chloride.
Is this easier to convert to the carbonate?

Wait can you burn caesium Nitrate with sugar? You'll get caesium carbonate

When I opened this post and saw this reaction, I thought: Wtf?! Caesium nitrate + americium carbonate? Where did he get americium carbonate?!  Then I read further and saw that you are talking about ammonium carbonate . And realized that americium carbonate is Am2(CO3)3 .
Btw. ammonium carbonate is (NH4)2CO3, not NH4CO3, and caesium carbonate is Cs2CO3, not CsCO3.

Sorry, i was not thinking and wrote AmNO3, Am short for ammonium when i should have written NH4.
The Cs2CO3 i actually thought had formula CsCO3, i guess my lack of education really shows.
Burn caesium nitrate with sugar to get caesium carbonate?
What else gets produced?
Burning other nitrates with sugar was fun when one was younger, looked like a mini volcano.
But it didnt seem to be a clean burn.
Wouldnt it be better to use some simpler fuel molecule, or does burning CsNO3 and sugar produce relatively clean, easily separated Cs2CO3?

Cs oxalate somewhere claimed almost insoluble in water, other source 313 g per 100 ml of water at 20 C https://en.wikipedia.org/wiki/Solubility_table
