In chemistry what is the difference between ate and ite
The suffix -ide is only used if the nonmetal anion is monoatomic meaning one atom. Related questions How do you draw the lewis structure for polyatomic ions? The number of protons are not suppose to be equal to the number of electrons? How come we are How do you calculate the total number of protons and electrons in a polyatomic Ion.
Do you have Question e03c2. Question d. This is the general pattern. I don't know about you, but when I studied chemistry I was required to memorize a list of the most common ions, probably of them, their names, and their charges.
Figuring out the logic behind the naming helps a lot. Once you learn about oxidation states, remembering the charge is a piece of cake. There is an SO5! It's not nearly as common as sulfite and sulfate not by a long shot , so it doesn't necessarily fit into the nice little naming scheme. Edit: Also, just for clarity: the ite and ate don't have a relationship to absolute numbers of oxygens, just a relative amount. How many oxygen atoms an "-ite" represents is going to change depending on the primary atom.
Which means you're going to have memorize all of your most common polyatomic ions individually, if your instructor chooses to test on them. Mine didn't. I took high school chem but it was years prior to taking gen chem and I really got my ass kicked.
The fundamental book will have things explained a little more simply and hopefully provide some additional practice problems. Systematic naming always gives the oxidation state e.
Under IUPAC rules it's always "-ate" and if ambiguity could result more than one common oxide the oxidation state is given. Generally, however, if you're just doing things where there are two types, one with one more O than the other, we'll use "-ite" and "-ate" for them. As for SO5, it'd probably be something like "peroxosulfate" in common parlance, as one of the oxygens will be single bonded to another forming a small two membered chain.
I should think that the charge from the sulfur would be delocalized across the three singly bonded oxygens, giving them a 1. I never noticed this. Basically, when you have an anion that is a combination of a non-metal with oxygen. According to my book: It ends with -ate for the most common oxyanions of the element. In other words, what does it even mean by "most common"?
