What happened to the copper ions? Oxidation/Reduction?

What are oxidation and reduction ?

Redox reactions can be considered as electron transfer reactions. In an experiment a copper rod is dipped in AgNO_3 solution What happens to the colour of the solution and why?

Calcination isused to convert zinc carbon- ateinto zinc oxide. But cuproussulphate is converted into cuprousoxide by roasting: What happens to the ore when it is subjected to calcination?

What changes happen to the ions which are attracted to cathode?

Write equations showing oxidation and reduction.

What about the changes happening to the ions attracted to anode?

What happens to the Zn rod when dipped in copper sulfate solution?

a) What are the changes that can be observed with the iron rod and the color of copper sulphate solution if iron rod is dipped in copper sulphate solution? b) Write the equation of the oxidation and reduction reactions. c) What will be the change if silver rod is used instead of iron rod? What is the reason?

In a redox reaction, oxidation and reduction occur simultaneously. Write the classical concept of oxidation and reduction

Write the equations of the oxidation and reduction reactions.
