2008年的高考金属试题以元素铝、铁、钠为主体,多角度考查了金属的冶炼、性质及用途。命题特点是以金属为载体,联系氧化还原反应、计算、化学平衡、盐类水解、实验设计等知识考查综合能力。其热点题型主要有:(1)实验题。如宁夏卷第27题测试铁片样品中铁元素质量分数。(2)无机化工题。如上海卷第27题制 In 2008, the college entrance examination metal examination subject to the elements aluminum, iron, sodium as the main body, examined the metal smelting, properties and uses. Proposition features metal as the carrier, contact oxidation reduction reaction, calculation, chemical balance, salt hydrolysis, experimental design and other knowledge to examine comprehensive ability. The hot topics are mainly: (1) experimental questions. For example, in Ningxia Volume 27, test the iron element mass fraction in the iron plate sample. (2) Inorganic chemical problems. Such as Shanghai Vol.27 title system
