|
Electronegativity |
Fluorine is most electronegative and it decreases as it goes down the group |
|
|
Reactivity group 7 |
Become less reactive going down so halogens can displace halogens below it |
|
|
Reducing power of halogens |
Increases down the group as the outer electrons are far away and so easier to donate |
|
|
Halide ions and sulfuric acid |
Fluorine and chlorine - produce HF/HCl and product Bromine starts the same but will then create Bromine, sulfur dioxide and water Iodide also makes H2S |
|
|
Test for halide ions |
Add silver nitrate No precipitate =fluoride White precipitate =chloride Cream precipitate = bromide White precipitate =iodide |
|
|
Ammonia with silver nitrate |
Cl dissolves in both Bromide dissolves in concentrated ammonia I do sent dissolve on either |
