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

Ans: Rate of dissociation is high in the case of silver nitrate as it is ionic molecule where as Sodium argentocyanide or potassium argentocyanide is complex molecule. During the dissociation o...

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 ?

a)  The two ions are OH- and SO4-2 ions
b)  The main product that is formed at anode is oxygen gas
      Reaction at anode: 2H2...

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?

Ans: Arrhenius theory explains about dissociation of electrolytes in aqueous solutions.
  1. In the case of strong electrolytes, dissociation rate ...
