What is the product when zinc is added to sodium hydroxide solution?

intially:
Zn2+ + 2OH- -->Zn(OH)2
excess hydroxide:
Zn(OH)2 + 2OH- --> [Zn(OH)4]2-
It is true that excess hydroxide reacts further, but the reaction is as under:
Zn(OH)2 +2(OH)- ----> (ZnO2) 2- +2H2O or
ZnSO4 + 4NaOH ------> 2Na2ZnO2 +2H2O,
the white precipitate of zinc hydroxide dissolves with excess hydroxide and forms a soluble complex called sodium zincate. The solution becomes clear. No ppt.

∙ 12y agoIt is a precipitation reaction hence,
NaOH(aq)+ Zn(NO3)2 (aq)--> NaNO3(aq)+ Zn(OH)2(s)
this is the molecular equation
complete ionic is:
Na^+ +OH^- + Zn^2+ + 2NO3--> Na^+ +2NO3^- +Zn(OH)2(s)
net Ionic equation would be
Zn^2+ +2OH^- --> Zn(OH)2

Name the solution formed when sodium is added to water?
sodium hydroxide solution
Does sodium hydroxide release protons when added to water?
No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.

What happens when sodium hydroxide is added to copper sulphate solution?
Nothing
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
What happens when iron oxide is added to sodium hydroxide solution?
anything important

What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
It Turns Pink.
Why is sodium hydroxide is sometimes added to a vial of anesthetic solution?
There are times when bacteria, acidify an infected site, therefore adding sodium hydroxide will neutralize the region for a basic site.
