The formula for sodium zincate, Na2ZnO2, is derived from the combination of sodium (Na), zinc (Zn), and oxygen (O) ions. In the compound, the zinc ion has a +2 charge, the sodium ion has a +1 charge, and the oxygen ion has a -2 charge. By balancing the charges, you get the formula Na2ZnO2.
What else can I help you with?
How chemical symbol of sodium zincate is formed by valency?
The chemical symbol of sodium zincate is Na2ZnO2. It is formed by balancing the valencies of sodium (Na), zinc (Zn), and oxygen (O). Sodium has a valency of +1, zinc has a valency of +2, and oxygen has a valency of -2. By combining these elements in the appropriate ratios, the compound is represented by Na2ZnO2.
What is Product of zn plus Naoh?
When zinc (Zn) is combined with sodium hydroxide (NaOH), the reaction produces sodium zincate and hydrogen gas. The chemical equation is: Zn + 2NaOH -> Na2ZnO2 + H2.
Is sodium zincate an ionic or nonionic compound?
Sodium zincate is a name applied to a number of different compounds. A solution of zinc in sodium hydroxide forms a complex mixture of anions such as Zn(OH)42- Solids can be obtained such as Na2Zn(OH)4, Na2Zn2(OH)6 from solutions of zinc in NaOH Some mixed oxides of zinc and sodium such as Na2ZnO2 , contain tetrahedral Zn atoms which are considered to have some covalent character.
What are the products formed when granulated zinc reacts with caustic soda?
When granulated zinc reacts with caustic soda (sodium hydroxide), the products formed are hydrogen gas and sodium zincate, which is a soluble compound. The chemical equation for this reaction is: Zn + 2NaOH -> Na2ZnO2 + H2.
Why does NaOH react with zinc metal?
NaOH reacts with zinc metal to form sodium zincate (Na2ZnO2) and hydrogen gas (H2). This reaction occurs because NaOH is a strong base that can easily ionize in water to form hydroxide ions, which then react with the zinc metal to produce the desired products.
How is sodium Zincate formed?
Sodium zincate is formed by reacting zinc oxide with sodium hydroxide in water. The chemical reaction between the zinc oxide and sodium hydroxide results in the formation of sodium zincate, which is a compound containing both sodium and zinc ions.

What is formed when Excess of sodium hydroxide react with zinc?
This reaction is to be carried out with Sodium hydroxide dissolved in water and Zinc oxide. The product is Sodium Tetrahydroxidozincate(2-) or Simply Sodium Zincate.ZnO + 2 NaOH + H2O ----> Na2Zn(OH)4

What is the name of ZnH2O4?
ZnO is called zinc oxide, but the formula Zn2O2 is not a correct one for this compound.
What is the molecular formula of potassium zincate?
K2Zn(OH)4 because valency of Zincate [Zn(OH)4] is 2 Potassium (K) is 1
Why does sodium oxide plus zinc give sodium zincate plus hydrogen?
It doesn't. There is no source of hydrogen atoms in the equation, and there is no zincate. Sodium oxide plus zinc produces zinc oxide plus sodium. Na2O + Zn ---> ZnO + 2Na
What happen when zinc granules are add to NaOH?
In this case sodium zincate is formed.
How zinc oxide reacts with excess sodium hydroxide?
Zinc salt will form complexes of sodium zincate which is colourless and a clear solution would be observed
