Question

Strong, weak, or nonelectrolyte? how will I know?

propyl amine, potassium iodide and carbonic acid, what kind of electrolyte are they?

Answer 1

Answer 2

@Photon336 @Shalante

Answer 3

write these all out as chemical compounds first

Answer 4

ok..

propyl amine: \(CH_3CH_2CH_2NH_2\)
potassium iodide: KI
and carbonic acid: \(H_2CO_3\)

Answer 5

then..?

Answer 6

I think KI is a strong electrolyte.. because of K+ and I-

Answer 7

@owlet electrolytes usually produce ions in solution

Answer 8

Im not too sure about propyl amine, but if you look at it's structure you know that \(\sf CH_3CH_2CH_2\mathbf{NH_2}\) have hydrogen bonds, and hydrogen bonds take a lot of energy to break.

You are right about \(\sf KI\), therefore it's a strong electrolyte because it has an ionic bond, and ionic bonds are soluble in water.

for Carbonic Acid, \(\sf H_2CO_3\), ask yourself whether it's a strong acid, if it's a strong acid, then it's a strong electrolyte

Answer 9

I think acids are also considered electrolytes. and their strength depends on how many H+ ions are produced.

Answer 10

for acids and bases, the strength of their electrolytes depends on whether theyre a strong acid, or a strong base

Answer 11

okay.. just wanted to confirm.. if a substance is a strong acid/base then they are strong electrolytes?

Answer 12

yeah, because that means more ions are produced

Answer 13

Acetate, \(\sf HC_2H_3O_2\) is a weak electrolyte compared to let's say... nitric acid, \(\sf HNO_3\)

Answer 14

what about organic compounds, like glucose? they have H bonds also..?

Answer 15

@owlet question to you is that compound above hexane would that be considered an electrolyte?

Answer 16

and why?

Answer 17

i think it is nonelectrolyte because.. it doesn't ionize in water..?

Answer 18

yep

@owlet

another one,
which one is a better electrolyte and why?
