Is there an easy way to memorize the polyatomic ions and acids?
Oh, the woes of AP Chemistry summer assignments...
Answer:
Totally an easy way. Notice how the ions *tend* to have both the same ending and the same charge? (Some of them do not, so don't be fooled!) Also, notice how the endings vary if the charge is positive or negative?
Here's the best thing to do:
Create a table with the charges on the top (-4, -3, -2, -1, 0, +1. etc) and the components of the ion on the side (S, F, etc). Fill in the table with the appropriate charge and ending
SO52− persulfate ion
SO42− sulfate ion
SO32− sulfite ion
S2O32− hyposulfite
Note: Not all of the slots will be full, but you will start to notice dependible trends depending on the charge and the number of other atoms (such as oxygen) that it is connected to. Finally make flash cards, or make a fun little sentence to correspond to the endings.
Once you get it, it's really easy!
not really. but there are only like 7 strong acids and bases so thats easy.
remember polyatomic ions by charge and it becomes easy. if you know the endings (-ite, -ate, etc.) that helps also.
have fun...
An "ic" will give you an "ate" and an "ous" will give you an "ite." Excpet in binary compounds. Chloride, hypochlorite, chlorite, chlorate, perchlorate.
Alkali metals, alkaline earhs, trelides, tetralides, pnictides, chalcogenides, halides, noble gases.
It's a body of knowledge that colloquially originated before anybody knew what was going on. If phloroglucinol being 1,3,5-trihydroxybenzene that is also 1,3,5-cyclohexanetrione is burdensome, do something else. I think its cute.
When you need research in the worst way possible - Uncle Al's way.

Nothing finer than 3-D chemistry
2 = ide
3 = ade
3 = ite
4 = ate
i think thats right
