What is the chemical reaction when zinc is heated with caustic soda solution?

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:
Zn2+ + 2OH- ---> Zn(OH)2(s)
it only reacts with boiling water forming zinc hydroxide and hydrogen...
Zn + 2H2O ==> Zn(OH)2 + H2
Its fairly nonreactive.
Zn hardly reacts with cold water.
It does however react with steam (heated water) to produce zinc oxide and hydrogen gas:
Zn (s) + H2O (l) --> ZnO (s) + H2 (g)

Zinc dissolves in excess NaOH (caustic soda) to form soluble sodium zincate, Na2[Zn(OH)4] or Na2ZnO2.

Wiki User
∙ 12y agoZinc react with sodium hydroxide and the zinc hydroxide is obtained.
Wiki User

What is a chemical reaction that happens when a hot air balloon flies?
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
What chemical reaction occurred copper sulfate pentahydrate when heated?
The chemical decomposition is:CuSO4------ CuO + SO3
When marble is heated what is the chemical reaction and equation?
The equation is: CaCO3------CaO + CO2
Was heated butter in a frying pan a chemical reaction?
Yes it is because it is not reversible, and the butter changed colour.
When ammonium carbonate is heated water ammonia and carbon dioxide produce. what chemical reaction is occurring?
Decomposition
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
What happens when ammonium chloride solution is heated with caustic soda solution?
ammonia should release on heating.
Is heated plutonium a chemical reaction when heated?
A reaction of oxydation with the oxygen from air.
What is a chemical reaction that happens when a hot air balloon flies?
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
What happens when Benedict's solution is heated?
the necessary chemical reaction requires a high activation energy so it needs the extra push from being heated as opposed to leaving it a room temp
What happens to the chemical reaction when it gets heated?
It may speed up when heated.
Is there evidence of a chemical reaction when bubbles form on heated water?
Yes there is a chemical reaction called 'Effervecense'.
What happens to substances when they are heated?
They do something, or have a chemical reaction
What occurs when heated water becomes water vapor?
A chemical reaction
What chemical reaction occurred copper sulfate pentahydrate when heated?
The chemical decomposition is:CuSO4------ CuO + SO3
When marble is heated what is the chemical reaction and equation?
The equation is: CaCO3------CaO + CO2
What is the main advantage of using a warm solution over a cold solution in a chemical reaction?
When solutions are heated, molecules are excited and speed up. This increases the chance that they will "bump" into each other and react, thus increasing the reaction rate. Also, many reactions require a certain Activation energy in the form of heat to even start the reaction.
