NOTES<br />
Volatile acidity (gm/100mL Acetic acid) =(0.60xmL NaOH x N NaOH)–(0.60 x mL I 2 x N I 2 )<br />
= 0.60x[(mL NaOH x N NaOH) - (mL I 2 x N I 2 )]<br />
If NaOH is 0.10N and Iodine is 0.02N = (mL NaOH x 0.06) - (mL I 2 x 0.012)<br />
DISPOSAL<br />
Boiling with a dilute solution of sodium hydroxide should clean the inner chamber of the<br />
still. Boil with distilled water to remove all traces of sodium hydroxide<br />
Samples must be degassed prior to analysis.<br />
A blank may be run with DI water as a QC check.<br />
Neutralize with Kolorsafe neutralizer and discard in sink.<br />
