the iron removal efficiency was 91.2%,while by precipitating in the form of ferric hydroxide(70 ℃,pH=3.8),the iron removal efficiency was 98.1% However ,by these two methods ,the use of oxidant and neutralization reagents introduced unwantedNH+4 ,Na + ,Ca2 + into copper sulfate solution. ...
When iron filings react with copper sulfate solution, the color of the solution changes from blue to _. A. green B. red C. yellow D. purple 相关知识点: 试题来源: 解析 A。当铁屑与硫酸铜溶液反应时,溶液的颜色从蓝色变为绿色。铁置换出铜,生成硫酸亚铁溶液为绿色。B 选项红色不符合;C 选项...
A. iron sulfate B. copper oxide C. copper D. iron oxide 相关知识点: 试题来源: 解析 A。铁放入蓝色硫酸铜溶液中,溶液颜色逐渐变淡,是因为铁与硫酸铜反应生成硫酸亚铁。B 选项氧化铜不是该反应的产物。C 选项铜是被置换出来的,不是导致溶液颜色变化的原因。D 选项氧化铁也不是此反应的产物。反馈...
There will be a layer of copper C. There will be a layer of gold D. There will be no change 相关知识点: 试题来源: 解析 B。解析:铁比铜活泼,当把铁钉放入硫酸铜溶液中时,会发生置换反应,铁会置换出硫酸铜中的铜,所以铁钉上会有一层铜生成。不会有银层或者金层生成,A、C错误;因为会发生反应...
C. The solution becomes colorless. D. Nothing happens. 相关知识点: 试题来源: 解析 B。解析:文章中提到“when an iron nail is placed in a copper sulfate solution, the iron nail turns brownish and copper is deposited on the nail.”,即当铁钉放入硫酸铜溶液中,铁置换出铜,铜沉积在铁钉上。

In addition to iron some grades of copper, molybdenum, and tungsten is produced in this manner. Powders can be produced by a combination of vapor decomposition and condensation. The carbonyl processes for iron and nickel are the most common examples of this method. The metals react with carbon...
Palladium is also associated with a number of gold, silver, copper and nickel ores. It is generally produced commercially as a by-product in the refining of copper and nickel ores. Russia, South Africa, Canada, and the United States were the world’s leading producers of palladium in the ...
