The impossibility of 100% ionic bond
Recently, I read the definition of oxidation state on Wikipedia. It read that a 100% ionic bond is impossible. So what does a 75% ionic and 25% covalent bond mean at all?

An ionic compound dissociates into 3 ions of 3 different elements?
When an ionic compound dissolves in water and becomes ions.
1) Typically we see:
$\ce{AB ->}$ Ions $\ce{A+ + B-}$
$\ce{ABC ->}$ Ions $\ce{AB+ + C-}$
2) But how about the one below, is there any case that will fit the situation
$\ce{ABC2 -> A+ + B+…

Ionic bonds- are electrons transferred?
In an ionic bond, are electrons actually transferred from one atom to the other to form a positive and a negative ion OR are ionic bonds just extremely polar covalent bonds? Sorry if this seems like a simple question but I've heard this somewhere so…

will the autoionization of water reduce due to common ion effect?
When a weak acid is added to water , will the dissociation of water reduce due to common ion effect caused by increased H+ concentration due to acid , my text book said common ion effect is caused by a strong electrolyte
Moreover this doubt is a…

How do you explain the formula Fe3O4 using the ionic compound theory?
I don't understand at all how the ionic bonding in $\text{Fe}$$3$$\text{O}$$4$ works. The oxygens all together have $4(–2e)=–8e$ net charge. But we cannot give the three irons equal positive charges to balance this: $8/3$ isn't an integer!
And…

Why don't salt crystals attract each other?
If salt is made of ions in a giant lattice, surely if I have two crystals they would attract each other and fuse? Or maybe the ions can't get close enough to each other to attract, or the surface is made of a different, neutral material?

Expression comparing the Solubility of Ionic compounds
In chemical bonding, I am taught an expression that compares the Solvation Energy and the Lattice Energy of an ionic compound which is being dissolved in a polar solvent (could be water, could be something else).
The expression is:
$$\left\lvert r_+…

Why does NaCl dissolve in H2O despite its strong ionic bond?
If $\ce{NaCl}$ is such a strongly bonded ionic compound, why it does it disassociate so readily in $\ce{H2O}$? One would think that because of the very strong ionic bond it would not disassociate it all. Further, why do other compounds like…

Why does a Fluoride ion only have a -1 charge and not a -2 charge or more?
Transition elements can form ions with different charges. Why can't elements other than transition elements form ions with different charges? If it is a Fluoride ion, why does it have to be an anion of charge -1? Why can't it have a -2 charge, or…

Do individual crystals resulting from evaporating a mixture of two ionic compounds contain both cations/anions within the crystal lattice?
I have wondered this for awhile. Let's say I dissolve, without loss of generality, potassium chloride and sodium chloride in water, then evaporate the water. Would any of the resulting crystals consist of randomly dispersed potassium and sodium…

Ionic liquids and deep eutectic solvent cation vs anion shape
If we consider an ionic liquid of a deep eutectic such as the choline chloride type DESs, why are ionic liquids (and deep eutectics) with not very symmetric cations and very symmetric anions more common than ionic liquids which are the other way…

Ionic compound gases
Does any molecule containing only ionic bonds exist as a gas in room temperature? In the case of carbon dioxide, it is a covalent molecule which is a gas at rtp. Does the same apply for ionic compounds?

Why does an anion not only bind to a single cation?
When $\ce{Na}$ binds with $\ce{Cl}$ to form $\ce{NaCl}$, why does the Na bind with multiple $\ce{Cl}$'s and not only one? A Na-ion is positively charged due to donating an electron and a $\ce{Cl^-}$ion is negatively charged due to accepting an…

Why are electrons transferred in an ionic bond?
I've been taught at school that in an ionic compound like $\ce{NaCl}$, electrons are transferred from the $\ce{Na}$ to the $\ce{Cl}$ to form $\ce{Na+}$ and $\ce{Cl-}$ which both have full outer shells. But what causes these electrons to be…
