This table from my textbook (p. 20), shows nature of charge on particles of listed sols, in their original or natural form. What reasons can be attributed to these observations? Positively charged sols Hydrated metallic oxides are formed by hydrolysing metal halides, the oxides so formed prefe...
I learned in my textbook that zinc forms more stable complex ion with NH3 than OH- because NH3 has only one lone pair and that makes repulsion between d orbital electron in zinc and lone pair electron in ligand smaller in NH3 complex ion than in OH- complex ion. But I also learned that Al forms o...
I learned that $\ce{Hg2Cl2}$ is almost insoluble to hot water and $\ce{NH3}$ water in my textbook, but $\ce{HgCl2}$ dissolves well in water. I wanted to know the reason and searched for it. It's written on some website that thanks to low shielding effect of f-orbitals and the fact that Hg has ful...
In my textbook it was written that if you put alkali solution into Hg2+ solution you won't get Hg(OH)2 but you get HgO. And this is because Hg has high electronegativity and this makes polarization of O-H in virtual Hg(OH)2 big enough to make dehydration of Hg(OH)2. I couldn't understand the rea...
