What does K2CO3 dissolve in?
Water
Potassium carbonate/Soluble in
Is K2CO3 soluble in toluene?
† Apparently, toluene is not a suitable solvent for this reaction (6% yield), because K2CO3 was slightly soluble in toluene (entry 1). The use of ethanol as a solvent resulted in a higher yield (62%, entry 2) than toluene, but a lower yield than DMF.
Does K2CO3 soluble or insoluble?
Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution. It can be made as the product of potassium hydroxide’s absorbent reaction with carbon dioxide. It presents a large capacity to absorb moisture.
Why is K2CO3 soluble in water?
It is a white salt, which is soluble in water. It is deliquescent, often appearing as a damp or wet solid. Potassium carbonate is mainly used in the production of soap and glass….Potassium carbonate.

What is the solubility of K2CO3 in water?
Solubility in water (g K2CO3/100 g H2O): 105.5 at 0 °C; 108.0 at 10 °C; 110.5 at 20 °C; 113.7 at 30 °C; 155.7 at 100 °C Schultz H et al; Ullmann’s Encyclopedia of Industrial Chemistry. 7th ed.

What is the working capacity of K2CO3 / CC1?
K2CO3/CC1 (ed) using ethanediol as the impregnation solvent reached a CO2 working capacity of 1.46 mmol/g at 400 °C in the first cycle and 1.23 mmol/g after 10 cycles, twice the capacity of the commercial K2CO3/MG70.
Is the solubility of potassium carbonate soluble in methanol?
To prove it, potassium leaching during the transesterification reaction needs to be examined. Most previous studies focused on the solubility of potassium carbonate in methanol and potassium carbonate was reported to be soluble in methanol (Arzamendi et al., 2008; Platonov et al., 2002).
Which is the stable phase of K2CO3 hydrate?
K2CO3 forms several hydrates, of which K2CO3.1.5H2O is the stable phase in contact with the saturated solution from 0 °C to about 110 °C.
