Would this equation be correct?
« on: August 29, 2015, 11:23:18 PM »
So the question tells me that I have a water sample with Co2+ ions in it - I've figured out that the "final" equation is Co{2+} + SCN{-} = Co(SCN)4 {-2}

What I'm not sure of is what reagent to add to the water sample to give me cobalt(II) thiocyanate - this is what I think it is;

Add KSCN{-} as a reagent, so then it'd be Co{2+} + 4KSCN{-} = Co(SCN)4 {-2} + 4K

Then you write a net ionic equation, and split up soluble reactants and products into their component ions;

4K{+} + Co{+2} + SCN{-} = Co(SCN)4 {-2} + 4K{+}

And then you'd cancel out the potassium ions and end up with Co{2+} + SCN{-} = Co(SCN)4 {-2}

I have a strong feeling that what I've done is wrong - I'm just not sure what reagent to add so that I'd end up with the equation I need. Any help would be VERY appreciated!

Most of your equations are not balanced, and some of your formulas are wrong. Please try to correct them (consult your book, or wikipedia), chances are things will be correct after that.

For formatting of indices and charges please use the buttons above the edit field - SCN-, Co(SCN)42- is much easier to read.

I've tried correcting them, but that didn't exactly work, which is why I'm on this forum :-\

So, what is the formula of potassium thiocyanate?
