Why are group 13 compounds in the +1 oxidation state more ionic than those in the +3 oxidation state?
I know that for group 13 metals in the p block, the stability of +1 OS is generally more than the stability of +3 OS as it is energetically not favourable to attain the higher OS of +3 and such ions ...

What are the Ionic Properties of Co-ordinate Covalent Bonds? [closed]
In my 10th grade book, it says that
A coordinate bond has properties of both covalent and ionic bonds. Therefore, it is also called dative or co-ionic bonds.
I understand that it has properties of ...

Isn't my book doing this problem about ionic product wrongly?
Problem:
After adding a $\pu{150 mL}$ $\pu{6.7\times10^{-5} M}$ $\ce{NaOH}$ solution to a $\pu{100 mL}$ $\pu{2.5\times10^{-5} M}$ $\ce{FeCl2}$ solution, green colored $\ce{Fe(OH)2}$ precipitate is ...

If bond types are in reality intermixed, how come different bonds form completely different structures?
According to the bond triangle, compounds don't exist as solely ionic or solely covalent, but rather have ionic, covalent, and metallic character to them. So each bond type is connected and similar in ...

Isn't hydrogen chloride a salt, because it is an ionic compound? [closed]
So I just learned in chemistry that salts are ionic compounds.
Shouldn't,
$\ce{H+Cl-}$ be a salt since hydrogen ion has positive charge and chloride ion has negative charge? If $\ce{HCl}$ is a salt ...

Does lithium form ionic hydride? [duplicate]
It is stated in my chemistry textbook that lithium indeed forms lithium hydrides. However, significant covalent characters could be found in lithium hydrides (like least reactivity).
But in some other ...

Why is the thermal stability of calcium carbonate higher than that of magnesium carbonate even though lattice energy decreases down a group?
The difference in thermal stability of $\ce{CaCO3}$ and $\ce{MgCO3}$ can be explained using Fajans' rules, but why not using the lattice energy method?
Why is the thermal stability of $\ce{CaCO3}$ ...
