Naming and Polyatomic Ions

[Ashley Davis 1I]

1) Can we use something like cyano- and cyanido- interchangeably? I've seen both used in the solutions manual.

2) For the test, are we expected to know the charge of various polyatomic ions like sulfate, oxalate, etc.?

During my discussion section, our TA said that both naming styles can be used /accepted. Knowing the charge of the polyatomic ions will be necessary to find the oxidation state and write the formula, so yes?

Is it expected of us to memorize the polyatomic ions?

Is it expected of us to memorize the polyatomic ions?

I don't think it's expected to memorize the polyatomic ions yet! I think that will be expected later on in the course, but we haven't focused too much on it yet so I wouldn't worry about it until then (:

I think it is fine to use it interchangeably. It would be safe to memorize the polyatomic ions as we need their charges to find the oxidation number and create our formula. However, I don't think it's too imperative. Hopefully, they're providing it for the most part.

We do not need to memorize polyatomic ions as of right now for this course.

im pretty sure you can use them interchangeably
