Other dihalides are received upon heating lead(II) salts with the halides of other metals; lead dihalides precipitate to give white orthorhombic crystals (diiodide form yellow hexagonal crystals). [5] Thanks to the similarity, both allotropes can exist under standard conditions (beta with small (10−5 relative) impurities, such as Si, Ge, Mo, etc.). PbO reacts with acids to form salts, and with alkalies to give plumbites, [Pb(OH)3]− or [Pb(OH)4]2−. This white crystalline powder is more soluble than the diiodide, but less than the dibromide and the dichloride. Pyrolysis yields elemental lead and alkyl radicals; their interreaction causes the synthesis of HEDL. The dioxide is a powerful oxidizer: it can oxidize hydrochloric and sulfuric acids.
