Test Procedure of Soda Ash(Na₂CO₃)

Formula Number : Na₂CO₃

Molecular Weight : (23*2+12+16*3)=106

Characteristics   : Clear, colorless solid.

Determination of Percentage of Soda Ash/Purity :

Procedure-1:

a)      At first we have to weigh accurately 5.3 gm soda ash for making standard 1.0 N solution.

b)      Transfer it into a conical flask or any pot  and pour 100 ml distilled water and mix well.

c)      Take 10 ml Na₂CO₃ solution into a conocal flask.

d)      Add 2-3 drops of Methyl Orange indicator.

e)      Titration with 1.0 N Hydrochloric Acid(HCl) solution. Say A ml of HCl is end point to change yellowish color to light pink color.

Procedure-2:

a)      At first we have to weigh accurately 10.6 gm soda ash for making standard 1.0 M solution.

b)      Transfer it into a conical flask or any pot  and pour 100 ml distilled water and mix well.

c)      Take 10 ml Na₂CO₃ solution into a conocal flask.

d)      Add 2-3 drops of Methyl Orange indicator.

e)      Titration with 1.0 N/1.0 M Hydrochloric Acid(HCl) solution. Say A ml of HCl is end point to change yellowish color to light pink color.

Calculation-1:

                     Na₂CO₃(strength) % =

        

Suppose, we need to change color 9.9 ml HCl acid are required .

So strength of soda ash(Na₂CO₃)=

                                             =99%

Calculation-2:

                     Na₂CO₃(strength) % =

Suppose, we need to change color 19 ml HCl acid are required .

So strength of soda ash(Na₂CO₃)=

                                             =95%

Hardness Test:

Ø  At first we have to make 1.0 N solution of Soda Ash(Na₂CO₃) for testing water Hardness test.

Ø  To test water Hardness it need to follow water Hardness test procedure.

pH Test:

Ø  At first we have to make 1.0 N solution of Soda Ash(Na₂CO₃)for testing pH.

Ø pH is tested  by pH paper or digital pH meter

Ø Standard pH of Na₂CO₃ in 1.0 N solution state is 11.4

Specific Gravity Test:

Ø  At first we have to make 1.0 N solution of Soda Ash(Na₂CO₃) for testing specific Gravity.

Ø  Then we check density of Na₂CO₃ by  Hydrometer .

Ø  Specific gravity of Na₂CO₃ is =2.509.
