胡华浙江高级教师经典题时刻闪烁着智慧的光芒,跳动着高考的脉搏,值得品味;通过经典题的分析不仅可以强化我们的知识体系,更重要的是能从中学到解题的思想方法。经典题1已知常温时,反应2Fe3++Cu2Fe2++Cu2+在水溶液中能发生。将22.4g铜粉与三氧化二铁混合粉末加入到1mol.L-1的硫
Hu Hua’s classic title of senior teachers in Zhejiang sparkled with the radiance of wisdom and beat the pulse of the college entrance examination. It was worth savoring. Through the analysis of classic questions, not only can we strengthen our knowledge system, but more importantly, we can learn from the thought methods of solving problems. When the classical problem 1 is known at room temperature, the reaction 2Fe3++Cu2Fe2++Cu2+ can occur in an aqueous solution. 22.4 g of copper powder and ferric oxide mixed powder are added to 1 mol.L-1 of sulfur
