CHEMISTRY QUESTIOn?

Question

Write ionic and net ionic equations for the following reaction

Na2S(aq) + Na2SO4(aq) --->

someone please help me

Answer 1

Lykovetos has a really good point. Also if they are already (aq) then they should already be assigned charges.

In general, though, to answer these, first you must know that these are precipitation reactions, and that *net* inonic equations don't bother with the things in the reaction which are not involved in a chemical change. So your ionic eq will be very thorough, listing all the compounds give, but your net will only list the ones involved, not the "specttaor" ions.

let's look at an example:
potassium hydroxide and iron (III) chloride

KOH + FeCl3 --> K+ Fe+3 Cl- and OH-
THEN
K+ Fe+3 Cl- OH- --> KCL + Fe(OH)3

THAT is your ionic eq. But most of that doesn't interest chemists. We only want the reactive stuff.
So we only write the stuff we care about:

Fe3+ + 3OH- --> Fe(OH)3
(notice that the +3 charge of the Fe matches the (3) -1charges of the 3OH molecule)


YOURS:

(aq) would mean what YOU have is
4Na(+1) + S(-2) + SO4(-2) + H(+) + (OH)-

which I guess cld go to form sulfuric acid and sodium hydroxide but it wld also give you back your sodium sulfide
H2SO4 + NaOH + Na2S

So yeah, looks like something is wrong in the question...

Answer 2

I'd help, but you'd think my answer was wrong.

Thanks for the 2 points!!

Answer 3

Do your homework! You will not learn if someone else gives you the answer.

Answer 4

Go and check your original question. There is no reaction here.
