Controlling solutions
Free acidity:
.Take 10 ml of bath:
. Dilute in an Erlenmeyer flask with about 50 ml of distilled water.
Add 3-5 drops of methyl orange indicator.
Titrate with NaOH 0.1 N until red to yellow colour change.
The ml of NaOH 0.1 N consumed gives the bath score
A bath prepared at 20 g/l has a bath score of about 18.
