How do you tell the difference between sterling and nickel silver?
Nickel silver is an alloy of nickel, copper, and zinc, while sterling silver is an alloy of silver and copper. You can tell the difference between the two by looking for a marking such as "925," which indicates sterling silver's higher silver content compared to nickel silver. Sterling silver will also have a brighter appearance and may tarnish less than nickel silver.
How do you tell the difference between a zinc and bronze penny?
A bronze penny has a reddish-brown color due to its copper content, while a zinc penny has a silver appearance. You can also check the date on the penny, as pennies made before 1982 are bronze and those made after are zinc.
Why is zinc used in desilverisation of lead?
Zinc is used in the desilverization of lead because zinc has a higher affinity for silver than lead does. When zinc is added to molten lead containing silver, zinc combines with silver to form a zinc-silver alloy, which then floats to the surface for easy removal, leaving behind lead that is desilverized.
Will zinc react in silver nitrate solution.why?
Yes, zinc will react with silver nitrate solution. This reaction occurs because zinc is more reactive than silver, so zinc displaces silver from the silver nitrate solution to form zinc nitrate and silver metal.
How many moles of silver will be generated if 1.30 moles of zinc is placed into the silver nitrate solution?
If the reaction is stoichiometric, 1.30 moles of zinc will generate an equal number of moles of silver. This is based on the balanced chemical equation for the reaction between zinc and silver nitrate.

What is the difference between silver plate and silver on copper?
Both are silver plated, but silver on copper tells you what kind of metal is used as an underlay. Silver plated copper is more valuable than silver on a white metal or zinc underlay.
Why is zinc used in desilverisation of lead?
Zinc is used in the desilverization of lead because zinc has a higher affinity for silver than lead does. When zinc is added to molten lead containing silver, zinc combines with silver to form a zinc-silver alloy, which then floats to the surface for easy removal, leaving behind lead that is desilverized.
What is the difference between tinplate and galvanized?
The primary difference between tin plate and silver plate is in what they are made of and their application. Tin plate is usually applied via electroplating and silver plate is applied via Tollen's reagent.
What is the difference between zinc conversion coating and zinc passivation?
Doas anybody knows?
Will zinc react in silver nitrate solution.why?
Yes, zinc will react with silver nitrate solution. This reaction occurs because zinc is more reactive than silver, so zinc displaces silver from the silver nitrate solution to form zinc nitrate and silver metal.
What will be the product when zinc and silver nitrate undergo a single replacement reaction?
The product of a single replacement reaction between zinc and silver nitrate is zinc nitrate and silver. The zinc replaces the silver in the compound because it is more reactive, causing a displacement reaction.
How many moles of silver will be generated if 1.30 moles of zinc is placed into the silver nitrate solution?
If the reaction is stoichiometric, 1.30 moles of zinc will generate an equal number of moles of silver. This is based on the balanced chemical equation for the reaction between zinc and silver nitrate.
Zinc reacts with silver nitrate gives zinc nitrate and silver?
In the reaction between zinc and silver nitrate, zinc displaces silver from the nitrate compound because it is higher in the reactivity series. This displacement reaction results in the formation of zinc nitrate and elemental silver.
What zinc and silver nitrate make?
Zinc Nitrate + Silver (Displacement Reaction= Zinc is more reactive than Silver)
What happens to zinc when dipped in silver nitrate?
Parts of the zinc near its interface with an aqueous solution of silver nitrate dissolve into zinc cations in the soution, and the corresponding electrical charge of silver cations is reduced to metallic silver, usually adhering to the surface of the remaining zinc.
