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.
