Question

which of the following solutions will have the highest electrical conductivity?
A.0.065M Na3PO4
B.0.075M (NH4)2CO3
C.0.10M LiBr
D.0.10M NaI
E.0.10M KF
Can someone please explain it to me.

Answer 1

in a solution, electrical conductivity is created by ions. The more ions the more electoral conductivity.

find which solution produces the most ions

Answer 2

How would i find out which one processes more ions?

Answer 3

use the molarity and it's dissociation equation

for example: \(NaI\rightarrow Na^+ +I^-\) produces 2 ions

0.10M *2 ions = 0.2 M

find moles, the find # of ions

Assuming were using the same volume of all solutions: 1L

0.2 M*1L = 0.2 moles -> 0.2 moles * 6.022*10^23 = 1.2044*10^23 ions

Answer 4

okay thanks

Answer 5

no problem
