这是我的 《A Level 化学易错题系列》的第 6讲。 A level 有不同的考试局,比如CIE, Edexcel, AQA和OCR,咱们国内主要是前三个考试局。其实也只有前三个考试局才在非英国本土开放,其中以CIE和Edexcel考试局为主。 虽然都是英国的考试局,但是不同考试局的大纲内容并不完全一样,要么内容有些许差异要么同样的内
Ab initio, model and empirical potentials for the interaction of rare gas atoms and halide ions are tested by their ability to reproduce gaseous ion transport data. The ab initio potentials are in poor agreement with the data. The model potentials give good agreement with experiment for some ...
A test device and method of use for determination of aqueous halide ions is described. The device has a porous matrix containing a silver dichromate reagent that gives a colorimetric response in the presence of halide ions and a cationic substance that prevents the formation of silver oxide ...
Research has demonstrated that in addition to the halide ion chloride; fluoride ions, when deposited and concentrated on the surface of austenitic stainless steel, can contribute to external...View More scope: 1.1 These test methods cover laboratory procedures for the determination of water-leachable...

BAmong halide ions, iodide is the most powerful reducing agent CFluroine is the only hologen that does not show a variable oxidation state DHOCl is a stronger acid than HOBrSubmit Which of the following statement is not true ? AThe partial pressure of oxygen in deoxygenated blood is 40 mm...
Why is it necessary to test the halide ions for their color in mineral oil? Why do metallic compounds conduct electricity as a solid? Explain the difference (or similarity) in the conductivity of tap water and distilled water. How could you test for mercury, silver, and copper(II) in wate...
What are some major assumptions to identifying halide ions? What is electrolysis? State its industrial application. Why does RbBr + NaCl form no chemical reaction? How do you know this? How do you know if something is an ionic compound by the way it reacts? What is analytical chemistry?
