What Type of Reaction Occurs Between Fe(NO3)3 and KSCN?
Dec 4, 2011 · 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...
How Does Adding KSCN Affect Fe3+, SCN-, and FeSCN2
Dec 15, 2016 · I just need clarification to see if I'm doing this correctly. When we add KSCN to a test tube with the stock solution the solution went from orange to yellow. When it asks about how the concentration changes, it changes because there is more KSCN added. Meaning there will be more SCN-(aq), would this be correct? Pertaining to the question what ...
Iron(III) Chloride and Potassium Thiocyanate reaction - Physics …
Mar 19, 2009 · Homework Statement I need to know the reactants of an iron(III) chloride and potassium thiocyanate reaction. Homework Equations FeCl3(aq) + KSCN(aq) =?? The Attempt at a Solution i think it is thiocyantoiron ion and potassium chloride, but …
Correlate the observations with Le Chatelier's principle? - Physics …
Feb 27, 2010 · 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 ...
Adding KNO3 and seeing color change - Physics Forums
Dec 21, 2010 · 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-].
How Does Adding KSCN Affect the Fe^(3+) and SCN^(-) …
Nov 2, 2004 · 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.
Calculating Volumes to Prepare Standard Solutions with KSCN
Jan 29, 2012 · 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.
Equilibrium: Iron(III) as Indicator for Ag+ Concentration - Physics …
Nov 2, 2005 · When Ag+ ions re added to the red FeSCN2+ ions, the color disappears, and white precipitate of AgSCn forms. Explain why the Iron(III) can be used aws an indicator in a reaction to determine the concentration of an unknown solution of Ag+ by reacting it with a solution of KSCN of known concentration. (the system is at equilibrium as well) thanks
Chemical Equation of Redox Reactions - Physics Forums
Feb 27, 2011 · Shake the solution. Test the presence of iron (III) by adding a drop of potassium thiocyanate, KSCN. Iron (III) gives a dark red solution if present. 3. Put iron (III) chloride, FeCl 3, in a test tube and add potassium iodide, KI. Put a drop of potassium ferricyanide, K 3 Fe(CN) 6. Iron (II) gives a dark blue precipitate if present. 4.
