The oxidation state of phosphorus in hypophosphoric acid is + _____
Correct answer is 4

The molecular structure of hypophosphoric acid (\(\text{H}_4\text{P}_2\text{O}_6\)) is given by:

This structure shows two phosphorus atoms bonded to oxygen atoms and hydroxyl groups. The oxidation state of phosphorus (P) in hypophosphoric acid is +4, which is determined by considering the bonding of phosphorus with oxygen and hydrogen atoms in the molecule.
The oxidation state is essential for understanding the reactivity and the acidic nature of the compound.
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)

Cobalt chloride when dissolved in water forms pink colored complex $X$ which has octahedral geometry. This solution on treating with cone $HCl$ forms deep blue complex, $\underline{Y}$ which has a $\underline{Z}$ geometry $X, Y$ and $Z$, respectively, are
