A copper coin is kept immersed in a solution of silver nitrate for some time. What will happen to the coin and the colour of the solution?

Academic Chemistry NCERT Class 10

When a copper coin is kept immersed in a solution of silver nitrate, the colour of the coin becomes shiny greenish-white due to deposition of silver on it.

What will happen if a strip of copper is kept immersed in a solution of silver nitrate (AgNO3)?
What will happen if a strip of zinc is immersed in a solution of copper sulphate?
When a student put some copper turnings in a colourless solution, he observed that the solution gradually turned blue. The solution is most likely to be :(1) ferrous sulphate solution (2) magnesium nitrate solution (3) silver nitrate solution (4) copper sulphate solution
Why does the colour of copper sulphate solution change when an iron nail is kept immersed in it?
A student was given two metal strips X and Y alongwith colourless silver nitrate solution to perform two separate displacement reactions. When the student placed metal strip X in silver nitrate solution for a considerable time, he observed that the solution turned blue and a coating of silver metal was formed on the strip. And when the student immersed metal strip Y in silver nitrate solution for an equal time, he observed that the solution turned light green with the formation of a coating of silver metal on the strip. The correct conclusion of the student about the identity of metals X and Y is :(1) X is copper and Y is magnesium(2) X is zinc and Y is copper(3) X is iron and Y is copper (4) X is copper and Y is iron
In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.
Which of the following pairs cannot undergo displacement reaction?A. iron sulphate solution and magnesiumB. zinc sulphate solution and ironC. zinc sulphate solution and calciumD. silver nitrate solution and copper
Which of the following pairs will give displacement reactions?(a) FeSO4 solution and Copper metal(b) AgNO3 solution and Copper metal(c) CuSO4 solution and Silver metal(d) NaCl solution and Copper metal
Which of the following pairs will give displacement reactions?(a) NaCl solution and copper metal.(b) MgCl2 solution and aluminium metal.(c) FeSO4 solution and silver metal.(d) AgNO3 solution and copper metal
A coin and a piece of paper are dropped simultaneously from the same height. Which of the two will touch the ground first? What will happen if the coin and the piece of paper are dropped in vacuum? Give reasons for your answer.
What happens when silver nitrate solution is added to sodium chloride solution?(a) Write the equation for the reaction which takes place.(b) Name the type of reaction involved.
Gold dissolves in (aqua regia/aqueous solution of silver nitrate).
Which of the following solutions will not make the bulb glow in the figure?$(a)$. Sodium chloride $(b)$. Copper sulphate$(c)$. Silver nitrate $(d)$. Sugar solution in diluted water"
(a) Why are decomposition reactions called the opposite of combination reactions? Explain with equations of these reactions.(b) Express the following facts in the form of a balanced chemical equation:"When a strip of copper metal is placed in a solution of solver nitrate, metallic silver is precipitated and a solution containing copper nitrate is formed."
