General description

This test paper is used for the determination of arsenic or arsine. It is baded on the fact that arsine forms a colored coordination compound with mercury compounds. The test paper is exposed to AsH3, liberated with zinc/hydrochloric acid, by holding the paper either over the test tube or over the end of a gas exhaust tube.

white → brown-black. The color reaction is faster, when the paper is first moistened before being used to test for AsH3 in air.
