Fe3+ + 3OH- _____> Fe(OH)3
1. Add a small quantity of the FeCl3 solution into the Na2S(aq.). 2FeCl3+3Na2S=2FeS↓+6NaCl+S↓ the following is the ionic reaction equation 2Fe3+ + S2- = 2FeS↓+ S↓ 2. Add a small quantity of the Na2S solution into the FeCl3(aq.) 2FeCl3 + Na2S =2FeCl2 + 2NaCl + S↓ the following is the ionic reaction equation 2Fe3+ + S2- = S↓ + 2Fe2+
2(FeBr3) + 3(Cl2) --> 2(FeCl3) + 3(Br2)
There's no reaction to be expected.
Look up or calculate the molecular weight/molar mass of FeCl3. Then... 40.0 g FeCl3/MW FeCl3/0.275 L = M (concentration of FeCl3 in solution)
Take 1 ml FeCl3 solution. add ammonia solution drop wise till brown precipitate just form. Now again add FeCl3 solution till brown precipitate just dissolve. This is your Neutral FeCl3 solution.
FeCl3 + H2O4-2 +Zn
TJHe chemical equation is:2 FeCl3 + 3 Zn = 2 Fe + 3 ZnCl2
FeCl3 + 6KSCN --> [Fe(SCN)6]-3 + 6K+ + 3Cl- This is a complex ion equation. K has a charge of +1 and Cl has a charge of -1 but since these form an aqueous solution, they are seperated. Put together, the equation cannot be balanced.
I would do a reverse of the Ferric Chloride test. Take the FeCl3 solution and add a solution containing phenols in it. If red, blue, green, or purple colors form, you've got FeCl3.
Double replacement reaction
Assuming double displacement. FeCl3 + 3NaNO2 --> Fe(NO2)3 + 3NaCl
FeCl3 + NaOH
