Hint: Potassium Ferrocyanide is the inorganic compound with formula K4[Fe(CN)6].3H2O. It is the potassium salt of the coordination complex [Fe(CN)6]4. This salt paperwork has lemon-yellow monoclinic crystals.

Complete step by step solution:
The reagent is potassium Ferrocyanide K4[Fe(CN)6].
(a) Potassium Ferro cyanide reacts with Fe(III) ions to form a Prussian blue precipitate of ferric Ferrocyanide (Fe4[Fe(CN)6]3)
(b) Potassium Ferro cyanide reacts with Zn(II) ions to shape bluish white precipitate of Zn2[Fe(CN)6]
(c) Potassium Ferro cyanide reacts with Cd(II) ions to shape bluish white precipitate of Cd2[Fe(CN)6]
(d) Potassium Ferro cyanide reacts with Cu(II) ions to form reddish brown precipitate of Cu2[Fe(CN)6] Hence, it can be used to perceive special cation like Fe3+,Zn2+ and Cd2+ etc.
So, the statement is true.

So, enter 1.

Additional information:
Inside the laboratory, potassium Ferro cyanide is used to decide the attention of potassium permanganate, a compound often used in titrations based on redox reactions. Potassium Ferro cyanide is used in an cumulative with potassium ferricyanide and phosphate buffered technique to offer a buffer for beta-galactosidase, that's used to cleave X-Gal, giving a sparkly blue imagining where an antibody (or other molecule), conjugated to Beta-gal, has bonded to its target. On reacting with Fe(III) it offers a Prussian blue coloration. Thus it's far used as an identifying reagent for iron in labs.

Note: Potassium Ferro cyanide reveals many areas of interest packages in enterprise. It and the associated sodium salt are widely used as anticaking agents for each road salt and desk salt. The potassium and sodium Ferrocyanide are moreover used within the refining of tin and the separation of copper from molybdenum ores. Potassium Ferro cyanide is used within the production of wine and citric acid.
