Marsh test is a chemical test for detection of Arsenic in a given sample. Zn and HCl are added to the sample when Arsine is produced by the nascent hydrogen generated. The gas from the sample is allowed to pass through a heated glass tube and I arsine is present, it decomposes to yield a brown deposit of Arsenic metal.
