What happens when zinc is added to dilute sulfuric acid in a test tube?
When zinc is added to dilute sulfuric acid in a test tube, a chemical reaction occurs where zinc reacts with sulfuric acid to form zinc sulfate and hydrogen gas. This reaction is a redox reaction where zinc is oxidized to zinc ions, while hydrogen ions in the sulfuric acid are reduced to form hydrogen gas. The production of hydrogen gas can be observed as bubbles forming in the test tube.
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.
Is any reaction is between oxalate ions and zinc ions?
No, oxalate ions and zinc ions do not react with each other in a typical chemical reaction. Oxalate ions are not strong enough reducing agents to displace zinc from its compounds.
What metal can remove zinc from a solution?
A metal like iron or magnesium can remove zinc from a solution through a redox reaction where the more reactive metal displaces the less reactive zinc ions. For example, iron can displace zinc from a solution containing zinc ions to form iron ions and solid zinc.
What is the name of the compounds formed zinc sulphur and oxygen?
The compound formed by zinc, sulfur, and oxygen is zinc sulfite (ZnSO3), which is a salt that contains zinc ions (Zn2+) and sulfite ions (SO32-).
What is the test to conclusively identify zinc ions a solution?
NaOH

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.
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
Ions present in znbr2?
In zinc bromide (ZnBr₂), the ions present are zinc ions (Zn²⁺) and bromide ions (Br⁻). Each formula unit of ZnBr₂ consists of one zinc ion and two bromide ions, resulting in a balanced charge. The zinc ion has a +2 charge, while each bromide ion has a -1 charge, leading to overall charge neutrality in the compound.
How is electrolysis used in the extraction of zinc from its ore?
Electrolysis is used in the extraction of zinc from its ore by passing an electric current through a solution containing zinc ions. This process causes the zinc ions to gain electrons and form solid zinc metal, which can then be collected.
Why do you need one zinc ion and two fluoride ions for zinc fluoride formula?
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 there anything in the name zinc phosphide that indicates there are three zinc and two phosphorus ions in the formula?
No. However, if you know your ions you will know transition metals such as zinc will commonly form a 2+ ion. From its position on the periodic table you may also conclude the phosphide ion has a 3- charge. Balancing the charges results in a formula of Zn3P2.
