In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.
Why does the colour of copper sulphate solution change when an iron nail is kept immersed in it?
Which of the following is a combination and which is a displacement reaction?
- \[\ce{Cl2 + 2KI -> 2KCl + I2}\]
- \[\ce{2K + Cl2 -> 2KCl}\]
When a black metal compound XO is heated with a colourless gas Y2, then metal X and another compound Y2O are formed. Metal X is red-brown in colour which does not react with dilute acids at all. Gas Y2 can be prepared by the action of a dilute acid on any active metal. The compound Y2O is a liquid at room temperature which can turn anhydrous copper sulphate blue.
- What do you think is metal X?
- What could be gas Y2?
- What is compound XO?
- What is compound Y2O?
- Write the chemical equation of the reaction which takes place on heating XO with Y2.
- What type of chemical reaction is illustrated in the above equation?
Explain the terms with examples.
