Sodium carbonate (Na2CO3) also known as washing soda or soda ash is a sodium salt of carbonic acid. It is generally prepared by ammonia soda or Solvey process. A common source of sodium carbonate is the ashes of plants sometimes called soda ash.
PTTH release is apparently ultimately controlled by a number of factors, including photoperiod, size and nutritional state of the animal (see Section 3.2.1). Proximately, a number of studies have pointed out the likelihood that PTTH release is directed by cholinergic neurons synapsing...

dioxide is a rather weak acid, the process is driven by the low solubility of the sodium bicarbonate formed. The sodium bicarbonate removed by filtration and is converted to sodium carbonate by heating. The sodium carbonate is fed back into the rotary kiln, closing one half of thealkalinity ...
Sodium Sesquicarbonate Dihydrate a2CO3 • NaHCO3 • 2H2O --- Introduction:white needle-like crystal, easily soluble in water, good mobility, can flow freely, no viscosity.
Municipal sludge is characterized by high water content, fine particles, complex composition, rich in organic matter (with an average content of more than 28%). Due to its poor mechanical properties, the municipal sludge exhibits low compressive strength, weak shear strength, a tendency to deform...
Sodium lauryl sulfate is prepared by sulfation of lauryl alcohol, followed by neutralization with sodium carbonate. Application Sodium dodecyl sulfate(151-21-3) has excellent detergency, emulsification and foaming power, can be used as detergents and textile auxiliaries, and is also used as an anion...
Solid-state electrolytes instead of liquid electrolytes are considered to be the most direct and effective solution to solve the above problems. However, its practical application is still greatly challenged due to the poor interfacial compatibility between the all-solid-state electrolytes and the anode...
