Testing and Control Procedure
Total
Acidity
- Pipette
out 10 ml. bath solution and make it 100 ml. with distilled water
- Pipette
out 10 ml. Diluted solution into the conical flask and add 2-4 drops
of phenolphthalein indicator solution
- Titrate
this against N/10 sodium Hydroxide solution till light pink colour is
obtained
- Note
down the volume of the N/10 NaOH consumed.
