c) AgNO3 d) BaCl2​

Answer 1

Answer:

b) ammonium thiocyanate

Explanation:

please follow me and put

Answer 2

b) ammonium thiocyanate is the correct option.

• Fe (III) are also known as ferric ions.
• The identification of ferric ions is performed by reacting them with thiocyanate ions.
• The ions formed in reaction are [FeSCN]²+ and the chemical formula for ferric thiocyanate is Fe(SCN)3.
• The complex formed in reaction is of blood red colour.
• By the help of colorimetry, concentration of ferric ions can be calculated from the samples.
