What is the balanced reaction for the decomposition of zinc oxalate dihydrate to zinc oxide water and carbon dioxide?
The balanced reaction for the decomposition of zinc oxalate dihydrate to zinc oxide water and carbon dioxide is ZnCO3 --------> ZnO + CO2.
Why do you add zinc metal during titration of ferrous oxalate and potassium permangnate?
Zinc metal is added during the titration of ferrous oxalate and potassium permanganate to ensure that all the permanganate ions are used to oxidize the ferrous ions and not any other substances present in the solution. The zinc reduces any excess permanganate ions to colorless Mn2+ ions, allowing for a more accurate determination of the endpoint of the titration.
What is the chemical reaction between zinc and sodium hydroxide (NaOH)?
When zinc reacts with sodium hydroxide (NaOH), it forms zinc hydroxide (Zn(OH)2) and hydrogen gas (H2). This is a double displacement reaction where the zinc ions in the zinc metal swap places with the sodium ions in the sodium hydroxide to form the products.
Is ZnCO3 ionic?
ZnCO3 is a slightly soluble salt that forms through the reaction of zinc ions with carbonate ions. It has both ionic and covalent characteristics, with the bonds between zinc and carbonate ions being predominantly ionic.
What is the balanced equation for the redox reaction between zinc and hydrochloric acid (HCl) that forms zinc(II) ions and hydrogen gas?
The balanced equation for the redox reaction between zinc and hydrochloric acid is: Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g)

Chemical formula of zinc oxalate?
The chemical formula of zinc oxalate is C2O4Zn.
What is the balanced equation for the redox reaction between zinc and hydrochloric acid (HCl) that forms zinc(II) ions and hydrogen gas?
The balanced equation for the redox reaction between zinc and hydrochloric acid is: Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g)
What is the word equation for copper sulphate and zinc?
This is called a reduction / oxidation reaction:Reduction of Cu2+ to Cu , done by electron donation from Zn which is then oxidized to Zn2+.Sulfate ions (SO42-) do not take part in this, they're called: tribuned ions.
Zinc metal is added to a solution of silver nitrate?
In this reaction, the zinc metal will displace silver ions in the solution because zinc is more reactive than silver. As a result, zinc will oxidize to form zinc ions while silver ions from the silver nitrate will be reduced to form silver metal. This reaction is an example of a single displacement reaction.
What happens if you mix zinc with ZnCl2?
When zinc metal is mixed with ZnCl2 (zinc chloride), a redox reaction occurs. The zinc metal will react with the zinc ions in the zinc chloride solution to form zinc atoms, while the chloride ions will remain in solution. This reaction usually results in the formation of more zinc metal and zinc chloride.
Which redox reaction would most likely occur if silver and zinc metal were added to a solution that contained silver and zinc ions?
The most likely redox reaction would be the displacement reaction of silver ions by zinc metal, forming zinc ions and silver metal. This is because zinc is higher in the reactivity series than silver, so it has a greater tendency to lose electrons and undergo oxidation.
How does hydrochloric acid react to zinc phosphate?
Hydrochloric acid reacts with zinc phosphate to form zinc chloride and phosphoric acid. This is a double displacement reaction where the positive ions switch between the reactants to form the products.
What metal reacts spontaneously with a solution containing zinc ions?
Aluminum is a metal that reacts spontaneously with a solution containing zinc ions, displacing the zinc from the solution due to aluminum's higher reactivity. This reaction is known as a displacement reaction where aluminum replaces zinc in the compound.
