We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. INTRODUCTION:
Sodium Carbonate is the disodium salt
of carbonic acid with alkalinizing
property.
Chemical Formula: Na2CO3
Molar Mass: 105.98844 g
Mass Percent: Na 43.381 %; C 11.332 %;
O 45.286 %
5. Occurrence:
Occurs as Crystalline dehydrate.
A great amount of sodium carbonate occur
naturally only in arid regions because it has high
solubility in water.
the country that posses the greatest amount of
sodium carbonate is Egypt, whose land is vastly
dry.
12. Properties:
Hygroscopic means when it exposed to air, it can
spontaneously absorb water molecules.
Soluble in water
Slightly soluble in Alcohol
Alkaline Taste
Effervescence
When it is placed in a slightly acidic solution,
it decomposes and forms bubbles.
13. USES OF SODIUM CARBONATE:
The main uses of sodium carbonate are as
water softener, food processing aid, pH
modifier, swimming pool chemical and
electrolyte. It is also used in the manufacture
of glass, paper, soaps and detergents, and
many other useful chemicals.
14. MANY USES OF SODIUM CARBONATE
IN OUR DAILY LIFE
LAUNDRY SOAP.
DISHWASHER.
MOPPING SOLUTION.
UNCLOG DRAINS.
FRESHER DRAIN AND TRAPS.
HARDWATER DEPOSITS REMOVER.
15.
16. MANUFACTURING OF NA2CO3:
THE MOST COMMONLY TWO METHODS USED IN
MANUFACTURING OF SODIUM CARBONATE.
•LEBLANC PROCESS
•SOLVAY PROCESS
METHODS:
17. MANUFACTURING OF NA2CO3
LEBLANC MATHOD:
In 1775, the French Academy of Sciences offered a
prize for a process whereby soda ash could be
produced from salt. The French Academy wanted to
promote the production of much-needed sodium
carbonate from inexpensive sodium.
In 1791, the French chemist Nicolas
Leblanc patented a process for producing sodium
carbonate from salt, sulfuric acid, limestone, and
coal. First, sea salt (sodium chloride) was boiled in
sulfuric acid to yield sodium sulfate and hydrogen
chloride gas, according to the chemical equation
19. It involved two stages: production
of sodium sulphate from sodium chloride,
followed by reaction of the sodium
sulphate with coal and calcium
carbonate to produce sodium carbonate
20. First, sea salt (sodium chloride) was boiled in sulfuric acid to yield
sodium sulfate and ,
hydrogen chloride gas, according to the chemical equation
2 NaCl + H2SO4 → Na2SO4 + 2 HCl
Next, the sodium sulfate was blended with crushed limestone
(calcium
carbonate) and coal, and the mixture was burnt, producing sodium
carbonate
along with carbon dioxide and calcium sulfide.
Na2SO4 + CaCO3 + 2 C → Na2CO3 + 2 CO2 + CaS
The sodium carbonate was extracted from the ashes with water, and
then
collected by allowing the water to evaporate
21. SOLVAY PROCESS:
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:
22. ADVANTAGES:
1)It is cheap process.
2)Raw material easily available.
3)CO2 recover in Calcination tower and
Ammonia also recover in Ammonia
Recovery Tower.
4)Pollution free.
5)Only 1 waste product that is CaCl2
6)Na2CO3 of very high purities obtained.
7)Pakistan is self sufficient in Na2Co3.
28. Step 2:
Shift Brine in Ammonia
Tower/Absorber and make
Ammonical Brine.
+Ammonia(NH3)
=Ammonical Brine
29. Step 3:
In lime Kiln we decompose
limstone at high temperature
950–1100 °C by heating and make
quick/burnt lime and CO2. Then
pass CO2 gas in Carbonation
Tower from bottom.
CaCO3(s) ---->CaO(s) + CO2(g)
30.
31. Step 4:
After filteration of Ammonical brine passes it
to Carbonation Tower from the top.
(because ammonical brine is in liquid form
and CO2 in gas form)
NH3(aq) +H2O(l) + CO2(g) ----> NH4HCO3(s)
32.
33. Now
NaCl(aq)+NH4HCO3(s) ----> NaHCO3(s) + NH4Cl
because NaHCO3 is not easily soluble in water
therefore at low temparature below 15c NaHCO3 is
made in solid form.
34. Step 5:
Now we heat about 300c NaHCO3 so
we get:
2NaHCO3(s)---->Na2CO3(s) + H2O (g) + CO2 (g)
35. Step 6:
Now for Ammonia recovery
We dissolve CaO in H2O
CaO+H2O ----> Ca(OH)2
(slaked Lime)
