Zinc was in the solution. More active metals oxidize (tarnish), forming aqueous cations, while less active metals get reduced (often precipitating them if they reach the 0 oxidation state). Magnesium is more active than zinc and less active than strontium; neither would it tarnish in magnesium ions. Therefore, zinc was in solution. Solution Zinc was in the solution.
