Answer to Question #158392 in General Chemistry for John

Question

Both iron(II) sulphate and iron(II) chloride are

green solutions. Which of the following reagents

which can be used to differentiate both the

solutions?

A Lead(II) nitrate solution

B Ammonium chloride solution

C Silver nitrate solution

D Potassium hexacyanoferrate(II) solution

Answer 1

$AgNO_3$ white precipiate with Cl$^-$ ion not with silphate ion.

Lead(II)nitrate gives precipiate with both iron(II)sulphate and iron(II)chlorides.

Ammonium chloride forms no precipitate with both of them.

Potassium ferocyanide gives blue colour with both of them.

so we can say Silver nitrate can differentiate iron(II)sulphate and iron(II)chlorides.
