Answer» (i) Explain, why copper, though a good conductor of electricity, is a non-electrolyte. (ii) Name the gas released at the cathode when acidulated water is electrolysed. (iii) Explain, why solid sodium chloride does not allow electricity to pass through? (iv) Fill in the blanks: (a) As we descend the electrochemical series containing cations, the tendency of the cations to get _________ (oxidized/reduced) at the cathode increases. (b) The (higher/lower) __________ the concentration of an ion in a solution, the greater is the probability of its being discharged at its appropriate electrode.
