Titrimetric Determination of Aldehydes

Iodine solution concentration (mol/L) Blank titration (mL) Sample titration (mL) Analyzed sample volume (mL) Sample ABV (%)

Calculated aldehyde (mg/dm³ absolute alcohol) Your standard's limit (mg/dm³)

Enter your own limit — verify the exact figures for your specific GOST/technical regulation separately as needed.
