硫酸铬钾的工业生产方法可采用有机物还原法和二氧化硫还原法。 有机物还原法 将99%重铬酸钾和98%硫酸按理论量溶解于铬明矾母液后,在搅拌下缓慢加入木屑进行还原。反应温度控制不超过80℃,反应结束后,静置缓慢结晶,经离心分离母液后,把结晶用少量冷水洗涤,再经低温干燥,制得硫酸铬钾成品。其2K2Cr2O7+8H2SO4+40H2O...
Properties of chlorine gas Copper wire burns (brown smoke) in chlorine gas. Cu + Cl2 ignites CuCl2 After that, you can get a blue solution (dilute) from a green solution. 2. The intense combustion of Na in chlorine gas (brown smoke) 2Na + Cl2 ignite 2NaCl 3. Iron burns...
We put 5 cm3 of a 0.1M potassium dichromate solution into a test tube. That is, we take 10 ml of distilled water and according to calculations, we put 0.3g of K2Cr2O7. Then by using a pipette, we add drop by drop 1.0M NaOH, that we make by adding 0.4g of NaOH to 10 ml of ...
