WitrynaIn the case of trivalent ions such as La 3+, bulk concentrations in excess of 10 −5 M can neutralize a negatively charged surface and even lead to charge reversal wherein the cations continue to adsorb onto a surface that is already net positively charged (see Problem 3. 2 (ii)). WitrynaPositively-charged ions are cations; negatively-charged ones are anions. The most common soil cations (including their chemical symbol and charge) are: calcium (Ca ++ ), magnesium (Mg ++ ), potassium (K+), ammonium (NH 4 +), hydrogen (H +) and sodium (Na + ). Notice that some cations have more than one positive charge.
