Nitratesmo Test Paper

Description

For the rapid determination of nitrate and nitrite.  The white test paper turns red-orange in the presence of nitrate; lemon yellow in the presence of nitrite.

Directions for use
Dip Nitratesmo test paper briefly into test solution and apply excess liquid to a strip of filter paper. Dip the moistened test paper very briefly into conc. sulphuric acid and spread on a glass plate placed on white paper. In the presence of nitrate only, the paper turns red. If, in addition to nitrate, nitrite is also present (evidenced by yellowish-red colour), the interfering nitrite can be destroyed by using amidosulphoric acid.

Store in a cool, dry place. Avoid exposure to sunlight and moisture.
