Thankyou so much. I got my doubts cleared very well.

Thanks

I have read from a book that from the following reaction H2O + R-O- - - - - > R-O-H + O--H We can conclude that water is a better proton donor (Bronsted acid) than alcohol. But how did they conclude so? I can figure out the reason on basis of electronegativity concepts but how to do so from...

In metals either of the two cases exists- 1. Conduction band is partially filled and the valence band is partially empty. OR 2. Conduction and valence band overlap.

Do electrons in conduction band are only responsible for current? Don't the electrons in partially filled valence band capable of moving contribute to current? Material discussed-metals(conductors)

AgNO3 and NaCl dissociates into ions in aqueous solution and forms the products mentioned above which are more stable than the reacting compounds. Is this correct?

What's the reason for which double displacement reaction occur? Why there is a need for ion exchange between two compounds? They are already in a bonded state, a stabilised one. So what benefit would a double displacement reaction give? The ionic reaction AgNO3 +NaCl - - - - > AgCl(ppt) +...

That indeed was a good answer. I got my doubt cleared. Thanks for the help!

May I know what did you mean by artificial classification? Where did I go wrong in making that statement.

But the reactants in the galvanic cell which get used up while supplying electrical energy require electric current from an outer source when it comes to recharging... and which means that the reaction is non spontaneous in the reverse direction. So how can we say that it is an reversible...

Another question again!... Can we describe a secondary cell as a cell which works initially as a electrochemical cell and when it comes to recharging it functions as electrolytic cell?

Sorry for a delayed reply... I got that doubt cleared from my teachers. They said both the terms are same. The word Discharging in the content was just meant to elaborate the concept of gaining or losing electrons.

I was asking about the process of discharging (converting them to neutral atoms) the cation and anion in accordance with their discharging potential.

Is there any difference between process of discharging and process of electrolysis? (I found the products same in both the case when discharging and electrolysis process are carried out for NaCl aqueous sol.)
