Creation of potassium carbonate
I am trying to synthesize K2CO3+NaOH from .9 molar potassium hydroxide solution and powdered sodium carbonate. I was wondering if both
products would be perhaps soluble in the water so they would be difficult to separate in the solution.(just wondering) Also I was wondering if this
synthesis is even possible, I balanced the equations myself but I may be wrong.

Offhand, I think that reaction might be going the wrong way as far as solubility... the K2CO3 is much more soluble than the Na2CO3. I don't think
you could really extract the NaOH into alcohol, either, because KOH is a lot more soluble in alcohol than NaOH is.

Thank you! I knew it was probably going to have solubility problems.

f you want potassium carbonate then drawing air through KOH solution will make it easily and cheaply ( if not especially fast)

Adding carbonated water (H2CO3) to KOH may be faster and easier. You will have to buy the Seltzer water however, so not necessarily the cheapest
synthesis.
