Question

How can the conductivity of a salt solution be decreased?

A. Add more water to decrease the concentration.
B. Add more salt to increase the concentration.
C. Add more salt to decrease the concentration.
D. Add more water to increase the concentration.

Answer 1

@aaronq Is it A?

Answer 2

What relationship is there between ions and conductivity of a solution?

Answer 3

I'm not really sure. Can you please explain? @aar\

Answer 4

Ionic compounds, when dissolved in water, dissociate into ions. Ions can act as charge carriers in solutions, so the more ions present the more charge carriers and therefore the more conductive a solution is.

Answer 5

Ohh so it's B?

Answer 6

what will increasing the concentration of salt do to the conductivity?

Answer 7

Increase it?

Answer 8

right. Now re-read the question

Answer 9

D?

Answer 10

Crap, you know what it is A

Answer 11

Oh haha ok. Thanks :)

Answer 12

Adding more water decreases the number of ions in the solution

Answer 13

np!

Answer 14

Incredible....
