The oxidation number of N and Cl in NOClO4
My doubt is not about the solution itself, actually I was able to find the solution myself.
We could split NOClO4 as (NO+) + (ClO4-) and then proceed, but here I "knew" this split. Is there ...

Out of KCl, CaCl2, MgCl2, NaCl, which causes the greatest corrosion rate of iron and why?
I know that salts act as an electrolyte in a redox process and rusting of iron, where iron loses electrons and oxidizes, and oxygen gains electrons and reduces. I did an experiment with KCl, NaCl, ...

Is acidic character related to reducing power?
My book says that the acidic character of halogen acids increases on going down the group because the bond strength decreases, making it easier to release the $\ce{H+}$.
But I also know that $\ce{HI}$...

Why is fluorine a oxidising agent? [closed]
An oxidizing agent pulls the electron cloud of the substance being oxidized towards itself, for example:
$$\ce{F2 + 2 X- -> 2F- + X2}\qquad (\ce{X} = \ce{Cl}, \ce{Br}, \ce{I})$$
We also know that ...

Trend in reducing property of dioxides
I am not sure of the explanation for the following statement:
The reducing property of dioxides of group 16 elements decreases from $\ce{SO2}$ to $\ce{TeO2}$.
Is the statement valid? If yes, how ...

Reducing character of group 15 hydrides
It was given in my text book that reducing character of group 15 hydrides increases down the group. I am a bit confused about this. For $\ce{NH3}$ this is fine as I assume that:
$$\ce{NH3 -> N + H^...

Why does oxygen in OH- have an oxidation state of 2-?
I am watching videos on Khan Academy in order to go over redox reactions (a really weak area for me.) In Sal's video, "Oxidation state trends in periodic table" at 7:10, he says:
If you had to ...

Why is Iron (Fe) difficult to reduce?
$\ce{Fe^3+ + e- -> Fe^2+} \quad +0.77$
$\ce{Fe^3+ + 3e- -> Fe} \quad -0.04$
$\ce{Fe^2+ + 2e- -> Fe} \quad -0.41$
$\ce{Zn^2+ + 2e- -> Zn} \quad -0.76$
$\ce{Co^2+ + 2e- -> Co} \quad -0.29$...
