I don't wish to go into details and mechanisms, so please excuse me.<quoted text>
try answering my question for once, instead of being pompous
I am not surprised that you goofed up that ordinary bit of chemistry on citrate and citric acid considering your weak foundation in math and science.
As for your question on arsenic, well, once again I don't wish to explain since it'll take me into explanation about the 4 quantum numbers - n, l, m and s, crystal field splitting energy, valence bond theory and then I'll have to explain the nuances of oxidation state which you think you know but you don't - for instance, if I ask you to find the oxidation state of S in the transformation of sodium thiosulfate to sodium tetrathionate in acidic medium showing all the working steps you will not know how to begin. And, if I ask you to contrast that with valence, milliequivalents, moles and ppm you won't know how to proceed.
So, well, I will drop the topic and forget about it for now.
Maybe some other time.
But, I am really not interested.
When I was preparing for the IIT JEE in Grades 9 to 12, I always referred to advanced Chemistry reference books like Morrison and Boyd, Bruce Mahan, Cotton, Sareen and Sareen,- these books are mainly used by university students but students wishing to crack the IIT JEE have to compulsorily refer to these books in detail.
In-depth knowledge of chem or math will hardly take you deep into the nature of the reality nor will it make one a better person.
Ok, then, best regards.
