doctortang.comLab #13: Qualitative Analysis of Cations and Anions Objectives: 1. To understand the rationale and the procedure behind the separation for various cations and anions. 2. To perform qualitative analysis of two unknown solutions that contain various ions (cations and anions) and positively identify these ions using established schemes. Materials:
Cations and Anions - An Introduction to Chemistry
preparatorychemistry.com• Some anions and cations contain more than one atom. • Polyatomic ion = a charge collection of atoms held together by covalent bonds • For example, it is possible for a nitrogen atom to form covalent bonds to four hydrogen atoms, but to make this possible the nitrogen atom has to lose an electron, giving the collection of atoms a plus one
