NEET levelSingle correct optionDifficulty 1 of 3qc185

The precipitate obtained when ammonium hydroxide is added to $FeCl X_{3}$ solution (in presence of $NH X_{4} Cl$ ) is

Awhite $Fe (OH) X_{3}$
Breddish-brown $Fe (OH) X_{3}$
Cblack $FeS$
Ddirty-green $Fe (OH) X_{2}$

Answer: B

Iron(III) hydroxide is reddish brown. Dirty-green

Fe (OH) X_{2}

is for Fe(II) and FeS is not formed in group III.

Which of the following statements about chromium species are correct? JEE Advanced level
Select the correct statements (high-spin unless a strong-field ligand is stated). JEE Advanced level
The group reagent for group III cations (Fe^3+, Al^3+, Cr^3+) is NEET level
Addition of NH4OH (with NH4Cl) to AlCl3 solution gives NEET level
Potassium thiocyanate added to a solution of Fe^3+ gives NEET level
Assertion (A): In group III, solid or aqueous NH4Cl is added before NH4OH, and Mg^2+ then stays in solution. Reason (R): NH4Cl suppresses io... JEE Main level
