electrical conductivity
« on: June 29, 2006, 09:46:07 PM »
maybe my book is wrong again, i dont know
but anyway i just want to make sure what is the correct answer

Which of the following solutions will have the lowest electrical conductivity? 
A) 0.1M HF
B) 0.1M NaHSO3
C) 0.1M H2SO3
D) 0.1M NaF
 
the book said A, but i think it should be B
what do you guys think?


thank you

No, the concentration of ions in 0.1 M HF is much lower than 0.1 M NaHSO3.  HF does not ionize into H+ & F- very much, but sodium compounds will be fully ionized.  So, a solution of NaHSO3 conducts electricity better than a solution of HF.

oh , yeah, NaHSO3 is a solluable salt
i thought we based on this acid: HSO3-,
so i totally got the lesson wrong!  :-\

thanks for saving me!

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
