Zn does not reacts with water ... Elementary zinc does not react with water molecules. The ion does form a protective, water insoluble zinc hydroxide (Zn(OH)2) layer with dissolved hydroxide ions, according to the following reaction mechanism:it only reacts with boiling water forming zinc hydroxide and hydrogen... Its fairly nonreactive.he ion does form a protective, water insoluble zinc hydroxide (Zn(OH)2) layer with dissolved hydroxide ions, according to the following reaction mechanism: it only reacts with boiling water forming zinc hydroxide and hydrogen...

Only a metal higher in the reactivity series will displace another. A metal can displace metal ions listed below it in the activity series, but not above. For example, zinc is more active than copper and is able to displace copper ions from solution.hose metals that can displace H + ions from acids are easily recognized by their position above H in the activity series. The boundary between the metals that react with water and those that don't is harder to spot.
