Germanium(II) hydroxide is formed as a white or yellow precipitate when base is added to solutions containing Ge II, produced for example by the reduction of an acid solution of germanium dioxide, GeO 2, with hypophosphorous acid, H 3 PO 2, [2] or alternatively by hydrolysis of GeCl 2. [3]
Splint armor is most commonly found as greaves or vambraces. It first appears in a Scythian grave from the 4th century BC [ 1 ] then in the Swedish Migration Era ; [ 2 ] and again in the 14th century as part of transitional armour , where it was also used to form cuisses and rerebraces .
The hexagonal (d = 4.29 g/cm 3) form of germanium dioxide is more soluble than the rutile (d = 6.27 g/cm 3) form and dissolves to form germanic acid, H 4 GeO 4, or Ge(OH) 4. [6] GeO 2 is only slightly soluble in acid but dissolves more readily in alkali to give germanates . [ 6 ]
A left-arm vambrace; the bend would be placed at the knight's elbow An ornate German (16th century) vambrace made for Costume Armor. Vambraces (French: avant-bras, sometimes known as lower cannons in the Middle Ages) or forearm guards are tubular or gutter defences for the forearm worn as part of a suit of plate armour that were often connected to gauntlets.
2 Ge. Germanium cluster anions (Zintl ions) such as Ge 4 2−, Ge 9 4−, Ge 9 2−, [(Ge 9) 2] 6− have been prepared by the extraction from alloys containing alkali metals and germanium in liquid ammonia in the presence of ethylenediamine or a cryptand. [42] [44] The oxidation states of the element in these ions are not integers—similar to ...
