镁、铝及其化合物在工业及生活中有着重要而广泛的用途,特别是铝及其化合物的两性,在题目中的计算形式方法性和技巧性均较强,是金属及其化合物知识的重点与难点.代表题型有镁的强还原性、铝盐与强碱反应产物的讨论、天平平衡问题、含铝化合物沉淀图象题等.
Magnesium, aluminum and their compounds have important and wide-ranging uses in industry and life, especially the dual nature of aluminum and its compounds. The calculation forms in the title are both methodological and technically strong, and they are the focus of knowledge of metals and their compounds. With difficulty, the representative questions include the strong reducibility of magnesium, the discussion of the reaction products of aluminum salts and strong bases, the balance of the balance, and the precipitation of aluminum-containing compounds.
