Yes, it is a Lewis acid. To determine whether a salt is acidic or basic, try the following.
1. Figure out which acid and base would make the salt (in this case Fe(OH)3 and HCl).
2. Whichever of the acid or base is the stronger is what the salt will be. In this case, HCl is a strong acid, iron(III) hydroxide is a weak base, so the salt is acidic.

yes it is
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)
FeCl3 has the name iron III chloride
FeCl3 + H2O4-2 +Zn
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.
yes it is
FeCl3 ? 1.1 grams FeCl3 (1 mole FeCl3/162.2 grams) = 0.0068 moles of FeCl3 ------------------------------------
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)
FeCl3 has the name iron III chloride
FeCl3 +KSCN + AgNO3
FeCl3 + H2O4-2 +Zn
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.
No, pure FeCl3 is not aqueous.
why does salicylic acid give a positive test with FeCl3
.2M x V FeCl3=moles FeCl3 x 1mole Fe2S3/2mole FeCl3=moles of Fe2S3 x mm of Fe2S3/1 mole Fe2S3= g Fe2S3 x .65% yield. 2.75g Fe2S3/ .65= 4.23g Fe2S3/ 207.91= .02035 x 2mole FeCl3=.0407 moles FeCl3/ .2M FeCl3= .2035 L x 1000= 203.5 ml
FeCl2 for Iron II Chloride and FeCl3 for Iron III Chloride
what would be seen if you analyzed salicylic acid in FeCl3?
