Question

$K_4\left[Fe\right(CN{)}_6]$ is an example of a _____

• A. Simple salt
• B. Double salt
• C. Complex Salt
• D. None of the above

Answer 1

The correct option is C Complex Salt

$K_4\left[Fe\right(CN{)}_6]$ is complex salt. Complex ion, $\left[Fe\right(CN{)}_6{]}^{4+}$ will be represented in square bracket and is called coordination entity. This will exist as a distinct entity. It does not dissociate into simple ions.

Simple salts and double salts will dissociate into its simple ions.
