Study Notes

Ionic Compounds and Ions

NH4 is an ammonium ion, a positively charged cation
OH is a hydroxide ion, a negatively charged anion
HCO3 is a bicarbonate ion or hydrogen carbonate ion, a negatively charged anion
NO3 is a nitrate ion, a negatively charged anion
CO32- is a carbonate ion, a negatively charged anion (corrected from CO2-3)
SO42- is a sulfate ion, a negatively charged anion
PO43- is a phosphate ion, a negatively charged anion
CNT is not a valid formula, did you mean CN-, a cyanide ion, a negatively charged anion?
