What happens when copper wire is dipped in ferrous sulphate solution?
When copper wire is dipped in ferrous sulfate solution, a displacement reaction occurs where copper displaces iron from ferrous sulfate, forming copper sulfate and iron. As a result, the copper wire will become coated with a reddish-brown deposit of iron.
How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
What elements make up gunpowder?
tree elements.a nitrate, typically potassium nitrate (KNO3), which supplies oxygen for the reaction;charcoal, which provides carbon and other fuel for the reaction, simplified as carbon (C);sulfur (S), which, while also serving as a fuel, lowers the temperature required to ignite the mixture, thereby increasing the rate of combustion.
What happens on placing iron nails in a beaker containing Copper Sulphate?
when iron nails are kept in a beaker containing copper sulphate displacement reaction takes place.Iron is more reactive than copper so it displaces copper from the copper sulphate solution.Thus it becomes iron sulphate+copper
A silver spoon is kept immersed in an aqueous copper sulphate solution what changes will take place?
as silver is less reactive than copper the silver when immersed will loose its electrons and the copper will displace it. i apologize if it is the wrong answer.... this is actually a guess :P
What happens when copper rod is immersed in silver nitrate solution?
When a copper rod is immersed in a silver nitrate solution, a redox reaction occurs where copper displaces silver from the solution to form copper nitrate and silver metal. This is due to copper being higher in the reactivity series than silver. As a result, the copper rod will become coated with a layer of silver metal while copper ions from the rod will transfer into the solution.
How do you identify between aluminum nitrate and zinc nitrate when they are both in solution?
Zinc is most reactive of the three. So if you put a piece of zinc metal to the three solution you will observe, In the Zinc nitrate solution there is no reaction while others have. As zinc is most reactive of three, in will displace the respective metals out of their solution. If the zinc is coated with reddish covering, it is Copper nitrate. If is coated with silvery needles, the solution is Tin nitrate.Zn + Cu(NO3)2 ----> Cu + Zn(NO3)2Zn + Sn(NO3)2 ----> Sn + Zn(NO3)2Zn + Zn(NO3)2 ----> [No reaction]
Is it okay to drink from a teapot that has been coated with silver nitrate?
It is strongly not recommended !
What are the sensitized materials?
Sensitized Material-l Refers to the film and photographic paper that basically composed of emulsion containing silver halides suspended in gelatin and coated on a trasparent or reflective support
Why is a film dried during processing?
Modern film are made using a flexible clear plastic base over coated with gelatin. The gelatin is the glue that holds the light sensitive chemicals to the film base. Gelatin is chosen because it is flexible, transparent, and porous. When the film is immersed in water, the gelatin swells. In this swollen state the chemicals of the developing process can penetrate and circulate within the gelatin. Since the chemicals used to develop film are dissolved in water, they are able to easily travel within the gelatin structure and do their job. After the film is developed the wet film is dried. As the gelatin dries it shrinks back to its original size. In earlier times, egg whites were used in place of gelatin. Film makers would like to replace gelatin for this task with something other than an animal product. Gelatin is made from the bone and hides of animals. Because gelatin works and because it actually boosts the sensitivity of the film (higher ISO), no substitute for gelatin has ever been found. The mixture of gelatin with the light sensitive chemicals imbedded within is called an emulsion.
What is an aristotype?
An aristotype is a historical photographic printing process that involves printing images on paper coated with a light-sensitive emulsion of silver salts. It was popular in the 19th century for producing high-quality photographic prints.

What is the difference between Tylenol tablets and geltabs?
The geltabs are tablets which are coated with a smooth gelatin coating, (supposedly) making them easier to swallow than the plain kind.
Is there any type of solution which can give shiny looks to the fruits?
water wax or carnauba wax is often coated on fruits like lemons
What are the suggestions on getting professional Human Cardiac Microvascular Endothelial Cells?
Human Cardiac Microvascular Endothelial Cells from Creative Bioarray are isolated from human heart tissue. Human Cardiac Microvascular Endothelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based solution for 2 min and incubated in Creative Bioarray' Culture Complete Growth Medium generally for 3-7 days.
What happen to the silver plate when dipped in copper sulphate solution?
That's a good question. What didhappen to it?I wouldn't expect much of anything to happen, since copper is a more active metal than silver. In fact, a copper plate dipped into a silver nitrate solution should grow silver crystals as the copper ionizes and replaces silver in solution.
What happens if leaves of green plant are coated with oil?
The plant will not be able to take in sunlight and the plant will not be able to make food and die.
