对硫酸的稀释方法,至今在实验室应用古老的实验技术,将硫酸缓缓地加入水中,同时不断用手工震荡和搅拌。它的缺点是:既不适于大量稀释硫酸,又在小瓶中稀释有危险,而且拖长稀释和冷却时间……不能令人满意。据此,我们从实际工作需要出发,设计了一个极其简单的实验装置称之为改进稀释浓硫酸法。它不仅可以制备大量的硫酸供学生使用,而且可以在烧杯中直接制备,简介如下:装置与操作方法仪器:指形冷凝管,大烧杯,量筒,磁力搅拌器取直径为30mm,长为350mm 的耐热指形
As for the method of diluting sulfuric acid, the old experimental technique has been applied in the laboratory so far, and sulfuric acid is slowly added to the water while continuously oscillating and stirring by hand. Its disadvantages are that it is not suitable for diluting sulfuric acid in large quantities, but it is also dangerous to dilute it in a vial, and the delay of dilution and cooling time is unsatisfactory. Based on this, we have designed an extremely simple experimental device called Improved Dilution Concentrated Sulfuric Acid based on practical work needs. It not only can prepare a large amount of sulfuric acid for students to use, but also can be directly prepared in a beaker, the introduction is as follows: Device and method of operation Instrument: refers to the condensing tube, large beaker, measuring cylinder, magnetic stirrer to take a diameter of 30mm, a length of 350mm Heat resistant finger
