Sep 8, 2016 · This part was the theory. What about the practice? Well, ionic radii are even less well defined than covalent radii; it basically comes down to obtaining a crystal structure of a specific salt …

Nov 5, 2015 · There are efforts underway to develop ionic liquids for the purpose of reducing bauxite using exotic intermediates such as aluminum fluoride. However, the aqueous $\\ce{Al^3+}$ ion is …

Aug 9, 2014 · Now, it seems obvious that the size of Al3+ should be greater than that of Li+ No it does not. It is true that electrons repulse each other, however, they all are attracted towards the nucleus. …

Oct 26, 2013 · We could extend the acidic/basic nature of $\ce {Al2O3}$ to the Lewis acid/base theory. For more about this see this question which has been asked before: Recall the Lewis Theory of acids …

I find it difficult to understand why the Atomic radius of Ar A r is lower than the ionic radius of MgX2+ M g X 2 + and FX− F X, and higher than AlX3+ A l X 3 +. According to the tables I've seen:

Apr 27, 2017 · I came across this question: Which of the following is bigger? $$\\ce{K+, Ca^2+, Al^3+, S^2-, Cl-}$$ Now, I know that the radius decreases as the period progresses to the right and …

May 22, 2021 · Suppose that I wanted to electroplate Al(s) onto a Cu(s) Cathode, (using an Aluminium Nitrate solution and Al(s) anode). At standard conditions, Al(s) is the strongest reducing agent, which …

May 15, 2015 · Apart from the methods, Ringo already described, you can do a few other tests. Aluminium This is loosely translated from the German chemgapedia.de. Look at the pretty pictures. …

Jun 5, 2021 · Al3+ does not have any unpaired electrons, thus this cation exists only in the singlet spin state.

Sep 23, 2022 · 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 …
