Question

does zinc dissolve in distilled water.??​

Answer 1

Explanation:

see below

thermodynamically zinc should react with distilled water because its redox potential is -0,76 V while for neutral water is -0,42 V, so we should have:

H

. But cinetically this reaction doesn't occur (it need an high activation energy to develop a gas on its surface) unless there is an opportune catalyst.

So Zn is used to preserve iron from corrosion by covering the same iron with thin layers of zinc
