Is any reaction is between oxalate ions and zinc ions?
The zinc oxalate is formed - ZnC2O4.
How many sulfur ions are joined to each zinc ions in the compound zinc sulfide?
The chemical formula of zinc sulfide is ZnS - one sulfur atom.
Why do you need one zinc ion and two fluoride ions for the formula zinc fluoride?
In any ionic compound the charges of the ions must balance out to zero. The zinc ion has a 2+ charge while the fluoride ion has a 1- charge. So zinc fluoride must contain two fluoride ions for every zinc ion.
Is ZnCO3 ionic?
Yes. Zinc carbonate is ionic. It consists of Zn2+ ions and CO32- ions in a one to one ratio.
What is the flame test for aluminum?
Aluminium ions like Magnesium ions have no colour in a flame test
What is the test to conclusively identify zinc ions a solution?
NaOH

If zinc electrode is dipped in zinc sulphate the electrode will become positive or negative?
if it is dipped the zinc electrode looses the electron in to the solution as zinc ions and it attains negative charge on th electrode and it absorb the positive ions in the solution.so w can see a bundle of positive ions just around the zinc electrode
When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.

Does the element zinc have a positive or negative ion?
Zinc forms ions with +2 charge (Zn2+).
Which metal was oxidized by two other ions?
Zinc
How does Daniell cell produce electricity?
A daniell cell is a system comprising a copper container, a solution of copper ions, a porous pot, a solution of zinc ions and a zinc rod. When the zinc rod and the copper container are connected by a wire, the zinc rod is oxidised to zinc 2+ ions, which releases two moles of electrons per mole of zinc decayed. These electrons flow round the wire to the positive electrode, the zinc container, where the copper ions in the solution are reduced to copper metal. If components eg. A light bulb, are placed within the circuit, the electron flow from the zinc to the copper electrode will power the bulb.
What happens when silver nitrate solution is stored in zinc vessel?
Some of the silver ions from the silver nitrate solution are deposited as metallic silver on the contacted parts of the zinc vessel and are replaced by half as many zinc ions in the solution.
Could copper also cause zinc ions to precipitate?
No. Ions do not precipitate on their own. Since zinc is more reactive that copper it will replace copper. So placing zinc in a solution of a copper salt will cause elemental copper to precipitate.
