Answer:

The test for arsenic is based on the procedure in which all arsenic if present is converted into arsine (AsH3) by reduction with zinc and hydrochloric acid. The reaction of the issuing gases with mercuric chloride paper producers a yellow stain which can be compared with that produced from a known amount of arsenic.
