Question

Potassium ferrocyanide is an example of __________.

• A. Complex salts
• B. Normal salts
• C. Double salts
• D. Basic salts

Answer 1

The correct option is A Complex salts

A class of salts in which there are no detectable quantities of each of the metal ions existing in solution is called complex salt.

An example is $K_{3}Fe(CN{)}_6$, which in solution has $K^{+}$ but no $F{e}^{3+}$ because $Fe$ is strongly bound in the complex ion, $Fe(CN{)}_6^{3-}$.
