Q. What is the reaction between copper sulphate and zinc?
Answer: When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
Q. What happens when Cu reacts with znso4?
i.e. Zinc will displace copper from copper sulphate solution. Explanation: Zinc is more electropositive than copper. This indicates that Zn + cuCu2+ = Zn SO4 = +Cu is spontaneous.
Q. What will happen when zinc metal is added to copper nitrate solution?
Answer: It leads to formation of Zinc nitrate and copper metal. Explanation: So it displaces copper to form Zinc nitrate.
Q. What will happen if copper is added to silver nitrate solution?
When a copper wire is introduced into an aqueous silver nitrate solution, a single replacement reaction occurs. This means that it loses electrons and forms copper ions. These ions replace the silver ions that are present in the aqueous silver nitrate solution to form a new compound: copper nitrate.
Q. What is the Colour of solution of copper sulphate?
blue color
Q. What is the Colour of copper sulphate solution answer in one word?
When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.
Q. Why does the Colour of copper sulphate solution change?
Iron lies above in the reactivity series and thus more reactive than copper. As a result, the more reactive metal (iron) displaces a less reactive metal (copper) from its salt solution (copper sulphate solution). Hence, the change in color.
Q. What is the color of solution?
When universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. Acids cause universal indicator solution to change from green toward red. Bases cause universal indicator to change from green toward purple.
Q. Which salt is green in Colour?
Hydrated ferrous sulphate or green vitriol is the green coloured crystalline salt.
Q. What color is mno4?
). Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry. Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media….Permanganate.

| Iron(III), Fe 3 + | Orange-brown |
| Copper(II), Cu 2 + | Blue |
Q. What color is zinc ion?
Color of Transition Metal Ions in Aqueous Solution
| Transition Metal Ion | Color |
|---|---|
| Ti3+ | purple |
| Cr3+ | violet |
| Mn2+ | pale pink |
| Zn2+ | colorless |
Q. Is zinc a positive or negative ion?
Zinc most commonly forms positively charged cations with a charge of +2. Zinc will rarely form ions with a +1 charge but it will never form ions with a negative charge. As zinc is a metal, it generally forms metallic compounds with other metals.
Q. Can zinc form complexes?
Zinc cannot form an ion with an incomplete d sub–shell and is therefore not a true transition element. Zinc’s chemistry is determined solely by the formation of compounds in its +2 oxidation state, but it does form many complexes, though not as many as other transition metals.
Q. Is zinc a transition metal?
A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals – even though they are members of the d block. The zinc ion has full d levels and does not meet the definition either.
Q. How many bonds can Zinc make?
Zinc exhibits only the +2 oxidation state. It can give up two electrons to form an electrovalent compound; e.g., zinc carbonate ZnCO3. It may also share those electrons, as in zinc chloride, ZnCl2, a compound in which the bonds are partly ionic and partly covalent.
Q. What does zinc bond with?
It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen. It is used principally for galvanizing iron, more than 50% of metallic zinc goes into galvanizing steel, but is also important in the preparation of certain alloys.
Q. What is the most absorbable form of zinc?
Zinc is available in several forms. Zinc sulfate is the least expensive form, but it is the least easily absorbed and may cause stomach upset. More easily absorbed forms of zinc are zinc picolinate, zinc citrate, zinc acetate, zinc glycerate, and zinc monomethionine.
