How can I do this:

3KNO3(aq)+ Fe(SCN)3(aq) + NaOH(aq) <---> ?

what do you have to do? write the products it makes.

I don't know the products it makes. I have to figure out what adding all those produces. Im not sure its even possible?

yes it is possible. first of all write it into net ionic equation, and then write it into complete ionic equation

3K (+1) + 3NO3 (-1) + Fe (+3) + 3SCN (-1) + Na (+1) + OH (-1) <--------> 3K (+1) + 3NO3 (-1) + Fe (+3) + 3SCN (-1) + Na (+1) + OH (-1)

So they all would answer each other? Huh?

6KNO3+ 2Fe(SCN)3+ 3Na2SO4---->Fe2(SO4)3 ↓ppt red + 6KSCN (aq) + 6 NaNO3 (aq)

ohh yes, the difference is only in this problem ur adding sodium sulfate instead of sodium hydroxide. Basically it'll be better off that you first break it into ionization or i would say ionic equation and then looking at this example write the answer.

3K (+1) + 3NO3 (-1) + Fe (+3) + 3SCN (-1) + Na (+1) + OH (-1) <--------> 3K (+1) + 3NO3 (-1) + Fe (+3) + 3SCN (-1) + Na (+1) + OH (-1)

So they all would answer each other? Huh?

use the exchange methesis reaction

I'm going to state that my teacher has never said that word and I have never heard that word. I am in grade 12 chemistry and this question is part of a chem 12 equilibrium lab. Could you write out the final equation?

thats not our goal. We only help. we don't answer. I do understand that you haven't learned this word yet,give me a minute to solve this.

is this reaction at equilibrium?

Thanks shis, I really appreciate this.

KNO3(aq) + Fe(SCN)3(aq) + NaOH (aq)----> NaNO3+ Fe(OH)3 ↓ppt red +KSCN

I did my best helping you nick. I am just a student at a college.

3KNO3(aq)+ Fe(SCN)3(aq) + NaOH(aq) <---> ?

I don't know what is going on here nor do I know exactly what is to be done but some corrections are in order from what I see posted. First, I don't see any reason for KNO3 being in the equation. Second. Fe(SCN)3 will react with NaOH to produce Fe(OH)3 which is a red-brown flocculent precipitate. The net ionic equation is
Fe3+(aq) + 3OH-(aq) ==> Fe(OH)3(s)

Regarding the one with Fe2(SO4)3, that is not a red ppt. It is soluble in water.
I hope this helps.

Dude I totally appreciate this, you're a life saver (if you're shis?). I'll write what I can and ask my teacher the class before this is due. If he expected this college-level stuff I guess no body in my class could answer it except him. Again, thanks a lot shis.

Much appreciated shis, I wish I could do more than say thank you, but thanks!

Merry Christmas,

You're welcome, Nick! I'm glad I could help. It's always important to ask for clarification from your teacher if you're unsure about certain concepts or equations. Asking questions is a great way to learn and understand the material better. Don't hesitate to reach out to your teacher for further guidance.

I hope you have a Merry Christmas too! Good luck with your chemistry lab assignment!
