Common ions

Science questions not covered in Chem 14A and 14B. Try to limit questions to chemistry (inorganic chemistry, physical chemistry, organic chemistry, biophysical chemistry, biochemistry, materials science, environmental chemistry).

Common ions

Postby vaishali 1D » Fri Oct 05, 2018 8:56 am

I know that Professor Lavelle mentioned that we'll learn as we go, but is there any tips for memorizing common ions and their charges? I've always had trouble with that, even in high school chemistry. Thanks!

Something that really helps me is having a piece of paper on which I have all the info regarding common ions, (name, symbols/formulas) to reference while studying and doing homework. Over time you'll become more familiarized the more you use them, but it helps to have that as a reiteration.

When I had to essentially memorize them for AP Chem in high school, I paid close attention to the prefixes and suffixes because they usually have a pattern associated with them. For example, polyatomic ions ending with 'ate' have one more oxygen atom than polyatomic ions ending with the suffix 'ite'. Think Chlorate vs. Chlorite. Chlorate is ClO3-1 and Chlorite is CLO2-1. Hope this helps a bit! :)

Is there a list of all the common ions that we should know? I know a few but I'm not sure if there are more that I am missing.

The best tactic that worked for me would be taking small groups of ions and writing each one four or five times in a unique color. I did this my sophomore year of high school and it has helped me remember the ions even today.
