Preparation of sodium bicarbonate and sodium carbonate?

Question

KHC4H4O6 + NaHCO3 will yield ??
HC2H3O2 + NaHCO3 will yield ??

Answer 1

Did you really need to ask five different questions in five minutes with the exact same title? Nobody will answer all of them!

a) Potassium hydrogen tartrate + sodium bicarbonate ===> potassium sodium tartrate + water + carbon dioxide

b) Acetic acid + sodium bicarbonate ==> sodium acetate + carbon dioxide + water

Answer 2

Preparation of NaHCO3:
NaHCO3 is mainly preparated by the old process, which entails the reaction of sodium chloride, ammonia, and carbon dioxide in water. It is produced on the scale of about 100,000 ton/year (year: 2001).

Commercial quantities of baking soda are also produced by this method: soda ash, mined in the form of the ore trona, is dissolved in water and treated with carbon dioxide. Sodium bicarbonate precipitates as a solid from this method:

Na2CO3 + CO2 + H2O → 2 NaHCO3
Production of Na2CO3 :

In 1861, the Belgian industrial chemist Ernest Solvay developed a method to convert sodium chloride to sodium carbonate using ammonia. The Solvay process centered around a large hollow tower. At the bottom, calcium carbonate (limestone) was heated to release carbon dioxide:

CaCO3 → CaO + CO2
At the top, a concentrated solution of sodium chloride and ammonia entered the tower. As the carbon dioxide bubbled up through it, sodium bicarbonate precipitated:

NaCl + NH3 + CO2 + H2O → NaHCO3 + NH4Cl
The sodium bicarbonate was then converted to sodium carbonate by heating it, releasing water and carbon dioxide:

2 NaHCO3 → Na2CO3 + H2O + CO2
Meanwhile, the ammonia was regenerated from the ammonium chloride byproduct by treating it with the lime (calcium hydroxide) left over from carbon dioxide generation:

CaO + H2O → Ca(OH)2
Ca(OH)2 + 2 NH4Cl → CaCl2 + 2 NH3 + 2 H2O
Because the Solvay process recycled its ammonia, it consumed only brine and limestone, and had calcium chloride as its only waste product. This made it substantially more economical than the Leblanc process, and it soon came to dominate world sodium carbonate production. By 1900, 90% of sodium carbonate was produced by the Solvay process, and the last Leblanc
