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?

Take Cupricchloride (CuCI_2) solution in a 'beaker. Dip two graphite rod in it. Pass 5V electricity through it: Why electricity passes through cupric chloride solution?

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?

Take Cupricchloride (CuCl_2) solution in a 'beaker.Dip two graphite rod in it. Pass 5V electricity through it: Write one word for the process of chemical change happening in a Electrolyte while passing Electricity?

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?

Take 25ml water in a beaker and pass electricity through it. The add little sulphuric acid in it. a) Why electricity didnot pass through pure water? b) What is your observation when H_2 SO_4 is added in water? c) Which type of ion formed more, when sulphuric acid is added in water.

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?
