Lecture 5 => Review of Lecture 4: True ionic charges may be obtained in dissolution of ionic compounds: e.g. from NaCl, Ca(NO 3 ) 2 , etc. Polyatomic anions are common: OH , PO 4 3 , ClO 3 , … Cation: NH 4 + . Polyatomic species usually remain intact in a chemical reaction, but under specific conditions, such as eating ey may ndergo reactions (decompose) heating, they may undergo reactions (decompose). Chemical reactions: customary to write with smallest integer coefficients (stoICHIometric coef.). They reflect the
