Soda ash (Na2CO3) Strength test

Soda ash (Na₂CO₃) Strength test

Make necessary solutions:

v  Hydro-chloric acid solution :

Process:

8.33 ml (12N LAB) HCL + Rest of the amount water in 100 ml volume metric flax to make 100 ml 1 N HCL solution.

v  Soda ash solution :

Process:

100 ml Water + 1 gm Soda ash (That will be tested by lab) in conical flax.

Test process:

1.      Na₂CO₃ Solution keep in a conical flax and placed just below the borate.

2.      Than phenolphthalein indicator will be added in soda ash solution and solution become pink color.

3.      Borate will be filling by 1 N HCL.

4.      Than titration will be start.

5.      When the pink color will vanish than the titration will be start. Read the borate reading. (21 ml)

Calculation

Formula :

Example :

                                                                             =111.3 (Strength)

N.B:- Below 85 strength is not allow.

                     The strength of Soda ash is good.
