WebThese are monovalent anions, meaning they have a valency (combining capacity) with only one ion of hydrogen. Similarly there are bivalent anions, etc. An ion is an atom (or group of atoms) with an electrical charge. Anions are one of the two types of ions. The other type is called a Cation, having a positive charge. WebThe common metallic cations found in exchange positions in clay minerals are Ca +2, Mg +2, Na +, and K +. At low pH values H + replaces other cations. The order of replaceability of the common cations has been found to be: Li + < Na + < K + < Rb + < Cs + and Mg +2 < Ca+2 < Sr +2 < Ba +2. Bivalent cations enter the exchange sites preferentially ...
