Separation of 2 compounds ( Powder )
If the powdered compounds are of different density you can separate them based on density in a liquid that does not dissolve them. For example, if you want to separate caffeine (density=1.36 g/cm3) ...

Role of MnSO4 in permanganometric titration
Both the oxidating ion $\ce{MnO4-}$ and reducing ion $\ce{C2O4^2-}$ are anions and therefore electrostatically repulsing each other, what makes their reaction slow.
$\ce{Mn^2+}$ ions serve as catalyst,...

Stability of H3MnO4, H2MnO4, HMnO4
Manganese doesn't like to be in +5 and +6 O.S. and the acid form of hypomanganate and manganate anion cannot exist due to rapid disproportionation. So, they exist as salts of alkali metals. Manganese ...

Stability of H3MnO4, H2MnO4, HMnO4
One difference between manganese(V) and phosphorus(V) is the former can undergo disproportionation with higher manganese oxidation states available.
Not only $\ce{Mn^VO4^{3-}}$ but also $\ce{Mn^{VI}O4^...

what will happen if we add lithium cobalt oxide into water?is it true that molecule will break and lithium will make LiOH and CoO2?
There is no molecule of lithium cobalt oxide. There are negatively charged layers of $\ce{CoO2}$ intercalated with positive lithium ions.
$\ce{LiCoO2}$ and $\ce{CoO2}$ are extreme and unstable states ...
