Inorganic chemistry Definition and 45 Threads

I am trying to understand how certain endothermic reactions work as a layman. I found the idea of reducing a rock to separate atoms fascinating, like what you would see in a comic book. However, I struggled to wrap my head around what that process would be like. I did some preliminary research...

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the d-orbitals rather than the lone-pairs cause d-orbital splitting energy?

Since I can't find a definition I just drew cycles. When to start and end?

I find the one (4s) + 3(4p) + 2(d) incorrect according to my knowledge.

I've been tasked with writing an equation to show the reaction of the Fe2+ complex with Cl2. I believe that the oxidation state of the Iron has changed, so I would write 2Fe(H2O)(6)^2+ + Cl2 -> 2Cl- + 2Fe(H20)(6)^3+, but I can't be sure this is correct. Is the 2Fe(H20)(6)^3 ion not yellow in...

I'm a weak student in chemistry, by 'weak' I mean I lack some base I think. May please suggest some good books on inorganic chemistry? I want to study p-block, d- and f-block elements along with their important compounds and their preparation. Book should be concise as for me as a weak student...

Hey i am currently doing my bachelor's degree in Science. I have a biology background but i am very much into chemistry, specially organic chemistry and conceptual physics. I hope all the great people here will help me with my queries and i would also be so nice if I could be of help to anyone.

I could finally get a copy of the Red Book 2005 from a library. In the chapter dedicated to nomenclature of coordinate complexes, while explaining the κ-system of specifying donor atoms, the following two examples were given (among many others): Can anyone explain how the naming is done for...

In searching through the literature for the solubility of calcium oxalate, I came across this post https://www.researchgate.net/post/Are_there_any_organic_inorganic_solvents_for_dissolving_Ca-oxalate I am not sure where the people answering this question have gotten the information that calcium...

BH4- + H^+ - > H2 + H2B6 Isn't hydride just a H -, simply putting that with an H+ should give a stable BH3 + H2. Why's the banana bonding happening? Also in NaBH4 + I2 - > B2H6 + 2NaI + H2, can i imagine a oxidation like 2BH4- -> BH3 + H2 + 2e? So I can break I2 as 2I -?

I don't get it, how did the sulfur get an oxygen, I'm unable to find any any half reaction wherein a oxygen ion is generated. So what is happening here?

doesn't make sense, h+ just has a really nice positive charge which is begging electrons but electrons go to the NO3(^2-) instead? why?

what just happened? if i did this in water could i do something like Zn + H2O > Zn2+ + 2OH- + H2 so you get ZnOH2 which gets another 2 OH added from NaOH to give Na2Zn(OH)4 nowwww... somehow this is dehydrated twice.. how? why? why is this less stable than the oxide?

Cheers everyone. Can the amount of water molecules added to a solution impact the formation of a salt with its ions mainly bonded through hydrogen bonds with electrostatic like behaviour? Let me give Some background to the question first: I am studying the precipitation of Phosphorous(P) as...

2Ca(NO3)2 -> 2CaO + 4NO2 + O2 Why is this happening? Are there any steps I can follow to get to the product? Something like with CaCO3 you remove CO2 because Ca polarizes the radical reducing bond strength.. Honestly I'm having a lot of difficulty with inorganic chemistry, id like to think...

Arrange the energy released upon hydration of Magnesium Oxide,calcium oxide,barium oxide,strontium oxide. I placed Magnesium oxide at the last,since magnesium hydroxide is a stable so lot of energy must be released in order to achieve that state,but the answer says calcium oxide.

We were measuring the amount of O2 dissolved in water by Winkler's method. Here's a link to the procedure and reactions: http://file:///C:/Users/SANJUKTA/Desktop/Downloads/Capture.PNG http://dropcanvas.com/6su7m/1 (The same is attached to this post) We had to use this formula: c(O2)...

I want a inorganic chemistry book. I require the book to be free because my requirement is only redox reactions. Buying a whole book would be a waste as I don't require other topics in the book. The book should contain tough exercises and possibly answers to some question if not all.

For inorganic chemistry, I am being asked to draw the solid state structure of polonium which i know how to do. However it asks what the symmetry of the unit cell is, and I don't know how to answer. I know what a unit cell is, I'm just not sure what the question means, or what it is looking for...

Its given in my book that Sulphuric acid displaces more volatile acid from Metal salts like NaCl. That is, NaCl + H2SO4→ HCl + Na2SO4 What does valtility have to do with such reactions? Or Should I just accept it as a fact?

I am looking for inorganic chemistry textbooks that covers topics on s,p,d block elements, metallurgy, qualitative analysis, and coordination chemistry. It should contain basic concepts like solubities of carbonates,sulphates, and should be at the level of "March's advanced organic chemistry" or...

Hi! I just read in an inorganic chemistry book (by Whitten, et al.) that acids are defined as substances that produce H+ ions in dilute aqueous solutions, and bases are those that produce OH-. To me, this definition implies that a substance that has yet to produce an H+ or an OH- can already be...

I'm tying to find any clue about the timescale of the biological pump. That the carbon is recycled to the surface ca. 1,000 years is clear but the timescale of the biological pump seems hard to find. There is an report I saw when I was surfing the internet saying that the timescale can range...

Alka seltzer contains 1916 mg of NaHCO3 and 1000 mg of citric acid. According to some descriptions of the reaction between alka-seltzer and water and then HCl (in stomach), there is an excess of NaHCO3 in the alka-seltzer in relation to the citric acid and the benefits from alka-seltzer come...

For group 15 elements the order of basicity given is NH3 > PH3 > AsH3 > SbH3 > BiH3 And order of reducing strength is BiH3 > sbH3 > AsH3 > PH3 > NH3 Why are they in opposite order? Reducing nature means tendency to donate electrons. Basicity means strength of bases and hence as basicity...
