Chemicals

Your experiment kit contains ﬁve chemicals: litmus powder,

which you will use to prepare the required litmus solution,

along with sodium carbonate, potassium hexacyanoferrate(II),

ammonium iron(III) sulfate, and tartaric acid. That sounds

complicated — but with a little practice you will be able to

pronounce the names quite easily, particularly if you read

them often in the manual.

Chemical vials

The chemical vials have one large chamber for larger

quantities and a smaller one for chemicals needed only in

small amounts. Fill levels are determined by what you

will need as well as by standards pertaining to

chemistry kits. The uniform size of the vials is

necessitated by the size of the labels containing

the information required by law. To open the

chemical vials, use the lid opener.

This is how you use the

lid opener to open a

chemical vial.

Tip:

When you open a vial, sometimes a

little of the chemical substance

will stick to the lid and fall on your

hand or the work surface. You can

prevent this by banging the

bottom of the vial several times

against the work surface before

opening it.
