Question

How do the conductivities of a 1.0 M KCl solution and a 2.0 M sugar solution compare?

A. The sugar solution has a lower conductivity because it has more ions in it.
B. The KCl solution is more conductive because the sugar solution does not conduct electricity.
C. The KCl solution is less conductive because it has a lower concentration.
D. The conductivities are the same because KCl splits into two ions in solution, doubling the concentration.

Answer 1

@JFraser It's C right?

Answer 2

it's not C

Answer 3

KCl and sugar are both soluble in water, but one is ionic and one is covalent

Answer 4

A?

Answer 5

when ionic solutes dissolve in water, they also \(dissociate\), falling apart into their separate ions

Answer 6

electricity can't flow if a solution has no free ions in it

Answer 7

B?

Answer 8

it is B
