We did these experiments in college to find out what type of ions they contained (anions or cations), but can someone explain to me as to how each of the tests actually work? I really need to know this... Test for chloride ion, Cl-. Known solution is sodium chloride. Test for sulfate ion, SO42-. Known solution is sodium sulfate. Test for hydrogen carbonate ion, HCO3-. Known solution is sodium hydrogen carbonate. Test for phosphate ion, PO4-3-. Known solution is sodium phosphate. there are some more but these will do for now.... I'd really appreciate any help

Hi there I was wondering if someone could give me a description of how the tests that you use to identify anions and cations actually works I did this experiment at college but don't know it actually works lol

Well, I can't write about what structure performs which function. I need to RELATE the structure to function. For example, the left ventricle is stronger than the right one because it has more work to do.

Hi people, I'm new here. I hope this is the right forum to post this in. Anyway, I need some help with my Bilogy assignment. I'm meant to relate structure to function for the digestive system, circulatory system, nervous system and respiratory system. I made a table with structure on one side and function on the other but apparently that's not good enough. Can someone help me to connect structure to function please?
