Jazakallah Khair...
in aqueous solutions...the one lower in the series is discharged, in this case OH- ions...it's B
because electrolysis of molten sodium chloride will only produce sodium and chlorine.
but the electrolysis of aqueous sodium chloride will form chlorine at the anode, hydrogen at the cathode, and sodium hydroxide. this is due to the presence of H+ and OH- ions as wells as Na+ and Cl-
hope this answers your question
no it doesn't have to be dilutein aqueous solutions...the one lower in the series is discharged, in this case OH- ions...
the thing you are saying is when the solution is concentrated but in the question, no where it is mentioned that it is concentrated which means it is dilute
what do you mean?no it doesn't have to be dilute
As you mentioned it has to be concentrated but the dilute solution gets concentrated due to the discharge of OH- and H ions....what do you mean?
umm...okie i get you..but why are we supposed to see/wait till all the OH- ions are over?As you mentioned it has to be concentrated but by time the dilute solution gets concentrated due to the discharge of OH- and H ions....
exactly!As you mentioned it has to be concentrated but by time the dilute solution gets concentrated due to the discharge of OH- and H ions....
it will occur. in the question it is asked which of the 2 solutions could form the 3 productsumm...okie i get you..but why are we supposed to see/wait till all the OH- ions are over?
hmm okie...Jazakallah Khair both of you..it will occur. in the question it is asked which of the 2 solutions could form the 3 products
