Re: Coordination compound
Two molecules of sulfate anions are attached to cations of potassium and aluminum. That's why it is called double salt.

Re: Coordination compound
Yes. Also can explain in this way. If compound is dissolved in water you can find potassium, aluminium and sulfat ions.
What is difference to K4[Fe(CN)6]. What will you find.

Re: Coordination compound
In potassium ferrocyanide, there are five molecules of iron and potash cations and only six molecules of cyanide anion.

Re: Coordination compound
No that is not the item we looking for. What happens if you dissolve the pottasiumferrocyanide in comparison of the potassiumaluminiumsulfate.
Think to the headline.
Write the equation in ionic form.

Re: Coordination compound
Coordination compound means a compound in which a molecule or ion formed by the bonding of metal atom or ion to two or more ligands by coordinate covalent bonds
Coordinate covalent bond means a bond formed when one atom provides both electrons in a shared pair.
Ligand means an ion or neutral molecule attached to a central metal ion in coordination compound.
2 K4Fe(CN)6 + 2 H2O = 2 K3Fe(CN)6 + 2 KOH + H2 📖
Chemical structure of K3Fe(CN)6 (Potassium Hexacyanoferrate(Ⅲ)) In the following structure, how many coordinate covalent bonds are present?

Re: Coordination compound
Sorry you have realy no idea.
KAl(SO4)2 => K+ + Al 3+ + 2 SO4 2-
We have two cathion and one type of anion. Means double salt.
K4[Fe(CN)6] => 4 K+ + [Fe(CN)6] 4-
We have only 1 type cathion and one type anion.
It is similar NaCl => Na+ + Cl- so no double salt.
Additional the complex what you have shown is K3[Fe(CN)6] is not the same what was asked in the original question.
The chemical equation is again nonsense. K4[Fe(CN)6] is very stable in water. There will be no hydrogen development.
