Keep two carbon rods immersed in copper sulphate solution.Then pass electricity through the solution: At which electrode does colour change occur anode or cathode?

Keep two carbon rods immersed in copper sulphate solution. Then pass electricity through the solution. i) At which electrode does colour change occur-anode or cathode? ii) Is there any change in the blue colour of the copper sulphate solution? iii) Write down the chemical equations for the changes occurring here?

Keep two carbon rods immersed in copper sulphate solution.Then pass electricity thr-ough the solution: Write down chemcial equations for the changes occuring here.

Keep two carbon rods immersed in copper sulphate solution.Then pass electricity through the solution: Is there any change in the blue colour of the copper sulphate 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?

What type of chemical changes happen when electricity is passed through brine solution?

Raju found that when a zinc rod is immersed in CuSo_4 solution taken in a beaker, the blue colour of the solution faded. Find the reason for the colour change.

Take Cupric chloride (CuCI_2) solution in a 'beaker. Dip two graphite rod in it. Pass 5V electricity through it: In which electrode oxidation and reduction takes place?

Write one word for a solution undergoes chemical change when electricity passes through it.

When acidified copper sulphate solution is electrolysed oxygen is obtained at the anode. What arrangements are to be made for this? Find the element deposited at the cathode.

Take Cupricchloride (CuCI_2) solution in a 'beaker. Dip two graphite rod in it. Pass 5V electricity through it: Which gas evolved out through positive electrode? How did you identify that gas?
