Hi Physics Forums,
I'm wondering if a distillation column is limited by the carnot efficiency and, if so, how this limitation can be used to determine the maximum efficiency of a distillation column with particular hot and cold side temperatures.
A distillation column has a hot and cold side...
I'm currently developing a waste heat recovery device as a side project. The system I've created uses a solution of acetone and water. One step in the process involves vaporizing acetone from the water at a low grade heat temperature (note: acetone does not form an azeotrope with...
If atmospheric pressure hot and cold air are sent into the opposing sides of a vortex tube (the ports normally used for gas outlet), will compressed air be generated/released from the hole/port normally used for gas input?
The reverse of the system above (cold and hot air enter from opposing...
Calcium Hydroxide is a stronger basic. However, in the Solvay Process Ammonium Bicarbonate + Sodium Chloride produces Ammonium Chloride + Sodium Bicarbonate.
Based on this, could Calcium Bicarbonate + Ammonium Carbonate produce Calcium Carbonate + Ammonium Bicarbonate.
I'm wondering if an aqueous solution of Calcium Bicarbonate and Ammonia would react to form Ammonium Bicarbonate and Calcium Hydroxide. Additionally, would Calcium Carbonate react with Ammonia in solution to form Ammonium Carbonate?
I'm testing Ammonium Bicarbonate in a fermentation process. Is it possible for Ammonium Bicarbonate to 'salt out' Ethanol? Compounds such as Sodium Carbonate and Ammonium Sulfate are able to salt out ethanol.
I'm writing a research plan for a college lab and I need the solubility of Ammonium Gas in Dimethyl Sulfoxide at STP and RTP. I've been searching internet and I haven't found anything. Please let me know the solubility or where I can find this information. Any help is greatly...
I know aqueous Ammonium Bicarbonate forms when NH4+ and HCO3- ions are present in water after they've dissolved from their gaseous states of NH3(g) and CO2(g). This occurs in the reaction:
NH3(g) + H2O(l) + CO2(g) => (NH4)HCO3(aq)
If Ammonia gas and CO2 are present above a polar organic...
Hi Physics Forums,
The solubility of a gas according to Henry's Law depends on partial pressure. Would an increase in pressure in a system increase the solubility of a specific gas, even if the partial pressure of that particular gas doesn't change?
The system described above increases in...
Why is CO2 released when soda is shaked, and dissolves again when the soda is stable?
My teacher in class today said that soluble gases will dissolve faster in the presence of agitation. In practice (e.g. shaking a bottle of soda), this seems to not be the case. Please explain
I'm currently doing a research project on diffusion. I've been thinking about how soluble gases can dissolve at higher concentrations in a colder liquid than a hot liquid.
If there are two connected containers, one with hot water and the other with cold water, and the cold...
