What Type of Reaction Occurs Between Fe(NO3)3 and KSCN?
2011年12月4日 · Homework Statement When Fe(NO3)3 and KSCN reated, it immediatly turned red. my teacher says this si the stuff they use for fake blood in movies. My problem is, we must state the reaction type. Homework Equations the products, I am assuming, are FeSCN and KNO3 (i know I did not yet balance...
Iron(III) Chloride and Potassium Thiocyanate reaction - Physics …
2009年3月19日 · In summary, the reactants for an iron(III) chloride and potassium thiocyanate reaction are FeCl3(aq) and KSCN(aq), which will form a coordination complex. However, the equation will not be balanced with a 1:1 ratio.
How Does Adding KSCN Affect the Fe^(3+) and SCN^(-) …
2004年11月2日 · In this case, adding extra KSCN will increase the concentration of the SCN^- ions, causing the reaction to shift towards the products side, resulting in an increase in the formation of FeSCN^2+ ions. I hope this helps! Let me know if you have any other questions.
How Does Adding KSCN Affect Fe3+, SCN-, and FeSCN2
2016年12月15日 · The kind of shift involved would be a shift to the left, towards the reactants.In summary, the experiment tested Le Chatelier's Principle by diluting a stock solution of FeSCN-(aq) with water and adding KSCN to one test tube. The concentration of Fe3+(aq) and FeSCN2+(aq) decreased while the concentration of SCN-(aq) increased when KSCN was added.
Correlate the observations with Le Chatelier's principle? - Physics …
2010年2月27日 · Test tube 2: a few drops of 0.1 M KSCN are added (the blood red color turns darker) Test tube 3: 25 drops of 6 M NaOH are added (the blood red color turns to yellow) Test tube 4: more distilled water is added (the blood red color becomes lighter in appearance)Okay, I'm confused when it comes to correlating my color observations of each test ...
Calculating Volumes to Prepare Standard Solutions with KSCN
2012年1月29日 · Calculate the volume of each reagent required to prepare 25.0 mL of each standard solution at the specified KSCN concentration. Fill in the rest of the table (attached). My complete guess is that the solution II needs to be incremented by 2.5 ml each time.
Using Le Chatelier's Principle for this equation, - Socratic
2017年8月5日 · Using Le Chatelier's Principle for this equation, #Fe^(3+) + SCN^(-) -> [Fe(SCN)]^(2+)#, which way would the equilibrium shift occur if #KSCN# was added?
Adding KNO3 and seeing color change - Physics Forums
2005年3月18日 · I have two aqueous solutions---Fe(III)(NO3)3 and KSCN (no precipitate in either, both are fully dissociated into ions). I react five drops of the ferric nitrate solution with one drop of KSCN (assume that we end up with excess Fe[3+]) The net ionic reaction Fe[3+] + SCN[-] (equilibrium arrows!) FeSCN[2-] forms a blood-red complex ion FeSCN[2-].
Question #0322c - Socratic
2017年7月13日 · Here's what I got. The trick here is that the iron(III) cations will combine with the thiocyanate anions to form the thiocyanatoiron(III) complex ion, "Fe"("SCN")^(2+). Now, you could say that the balanced chemical equation that describes this reaction looks like this "Fe"("NO"_ 3)_ (3(aq)) + 3"KSCN"_ ((aq)) -> "Fe"("SCN")_ (3(aq)) + 3"KNO"_ (3(aq)) However, that would not be …
