Lab III-2 of Biology Lab calls for ingredient missing in kit

[Jeff]

From lab III-2 in the Home Scientist Manual (both online and copy delivered by CDROM with kit): calls for missing ingredient.

Seliwanoff’s reagent

Seliwanoff’s reagent is used to discriminate ketoses

from aldoses. An orange to red color forms within five

minutes if a ketose is present. If the ketose is present in

low concentration, the color may be anything from a straw

yellow to yellowish-orange. Aldoses yield no color change

even after 10 to 15 minutes of heating.

If you’re using the kit, you can make up Seliwanoff’s

reagent by adding one part 6 M hydrochloric acid to one

part of Seliwanoff’s Reagent A solution. For example, to

make up 3 mL of Seliwanoff’s Reagent, use a graduated

pipette to transfer 1.5 mL of 6 M hydrochloric acid to 1.5 mL

of Seliwanoff’s Reagent A.

Hi, Jeff

I take it you mean the bottle of Seliwanoff's Reagent Part A was missing from your kit? If that's the case, please let me know and email me your mailing address. We'll get a replacement bottle in the mail.

Sorry for the inconvenience.

Best regards.

Bob
