As for the test. I have seen a person go and place metal in HCl on tv. The way they tested to see whether it was hydrogen gas was to collect the gas in a baloon as the Hydrogen gas was created. Then the sealed the balloon by tying it and subsequently lighted the balloon on fire (while standing very far away). Well, since hydrogen is very flamable, the balloon exploded.
Zinc chloride is a white solid which is soluble in the aqueous solution present in HCl.
