Will Ca(HCO3)2(aq) + 2NH3(aq) react?

AI Thread Summary
An aqueous solution of Calcium Bicarbonate and Ammonia may react to form Ammonium Bicarbonate and Calcium Hydroxide, with Calcium Hydroxide being a stronger base than Ammonium Hydroxide. The Solvay Process, which involves the reaction of Ammonium Bicarbonate with Sodium Chloride to produce Ammonium Chloride and Sodium Bicarbonate, raises questions about potential reactions between Calcium Bicarbonate and Ammonium Carbonate, possibly yielding Calcium Carbonate and Ammonium Bicarbonate. To confirm these reactions, calculating the exact equilibrium for the system is necessary. The driving force behind the Solvay Process is also a point of inquiry in the discussion.

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?

Which base is stronger, calcium hydroxide, or ammonium hydroxide?
 
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.

Good question. At first sight I would say yes, but to be sure you would need to calculate exact equilibrium for the system.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
