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...

How do you determine the enthalpy of vaporization of the acetone from the acetone-water solution?

Yes, acetone does undergo hydrogen bonding with water and that is the reason acetone is miscible in water. This paper details the binding energy between acetone and...

Hi Everyone, 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...

Is it possible to convert light in the visible spectrum to infrared or microwave light. What processes would be used to do this? Thanks, EJ

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.

Hi, 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? EJ

Does the Ammonium Bicarbonate decompose in the alcohol or is it able go separate the alcohol from the water? As an ionic compound, is it able to 'salt out' alcohol like other ionic compounds?

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.

Thank You!

Hi Everyone, 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...

During my summer chemistry course yesterday, I asked my teacher this question and she said she didn't know.
