On electroplating an article with silver we use sodium argentocyanide or potassium argentocyanide instead of silver nitrate as the deposition of silver is very fast andhence not smooth and uniform.How does use of silver nitrate, increase the speed of deposition?Explain

In electrolysis of aqueous copper sulphate using copper electrode we see that elctrons from copper anode gets transferred to copper cathode.So can we use any other electrolyte instead of CuSO4?Since we can't see any special use of CuSO4.Explain the reason.

Q. During electrolysis of an aqueous solution of sulphuric acid between platinum electrodes, two types of anions migrate towards the anode but only one of them is discharged :
(a) Name the two anions.
(b) Name the main product of the discharge of anion at the anode and write the anode reaction.
(c) Name the product at the cathode and write the reaction.
(d) Do you notice any change in colour. State why?
(e) Why this electrolysis is considered as an example of catalysis ?

One of the theory of electrolytic dissociation by Sir Svante Arrhenius is that:"The number of positive charge equals the number of negative charges in the solution and thus the solution is in electrolytic equilibrium.The equilibrium is also established between the un ionized molecule and the ions produced."
(i.).Is there any exception when the electrolytic equilibrium is not established?Explain with examples.
(ii.).How is the equilibrium is also established between the un ionized molecule and the ions produced?
