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 is the formula sodium hypochloride?
The formula for sodium hypochlorite is NaClO.
What is the valency of zincate?
Zinc has a valency of 2. It is represented by the symbol Zn.
What is the formula of the compound sodium dicromate?
The formula for sodium dicromate is Na2Cr2O7
What is the formula of sodium sulfide?
The chemical formula of sodium sulfide is Na2S.
How is sodium Zincate formed?
Formula: Na2ZnO2

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.
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.
What is the molecular formula of potassium zincate?
K2Zn(OH)4 because valency of Zincate [Zn(OH)4] is 2 Potassium (K) is 1
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
What is the valency of?
Zincate ion has the valency of 2 as the formula is [Zn(OH)4]2- or simply ZnO22-.
What happens when you add zinc dust to sodium hydroxide?
When you put zinc dust in sodium hydroxide solution, sodium zincate and hydrogen are formed. Zn + 2 H2O + 2 NaOH → Na2Zn(OH)4 + H2
What is the valency of ZnO2 in Na2ZnO2?
2
What is the chemical formula for sodium chloride sodium?
The empirical formula of sodium chloride is NaCl.
