Question: What is the formula for the complex formed between iron(III) and thiocyanate? (2021)
Options:
[Fe(SCN)3]
[Fe(SCN)2]
[Fe(SCN)6]3+
[Fe(SCN)4]2-
Correct Answer: [Fe(SCN)3]
Solution:
The complex formed is [Fe(SCN)3] as iron(III) can bond with three thiocyanate ions.

Questions & Step-by-Step Solutions
What is the formula for the complex formed between iron(III) and thiocyanate? (2021)
Step 1: Identify the oxidation state of iron in the complex. Iron(III) means iron has a +3 charge.
Step 2: Identify the thiocyanate ion (SCN). It has a -1 charge.
Step 3: Determine how many thiocyanate ions are needed to balance the +3 charge of iron. Since each SCN has a -1 charge, you need 3 SCN ions to balance +3.
Step 4: Combine the iron(III) ion and the thiocyanate ions to form the complex. You will have one iron(III) ion and three thiocyanate ions.
Step 5: Write the formula for the complex. The formula is [Fe(SCN)3].
