21. Aquo ions of divalent metal ions are less acidic than those of trivalent cations. 22. Some divalent copper generally replaces the zinc position. 23. The Vivianite Group is a group of monoclinic phosphates and arsenates with divalent cations. 24. Divalent anions may be symported with H +.25. It is a precursor to the coenzyme divalent or trivalent ions through the small intestine. 26. Working off of this effect, sodium cellulose phosphate will bind with divalent intestinal cations. 27. This pyridoxal-phosphate protein is activated by divalent metal cations ( e . g. 28. It transports both monovalent and divalent cations. 29. Divalent americium is obtained only in dry compounds and non-aqueous solutions ( acetonitrile ).30. Divalent europium is the source of the blue fluorescence, when seen in the mineral fluorite.
