Group 7 - the halogens - Edexcel Halogen displacement reactions …
Use the results in the table to deduce an order of reactivity, starting with the most reactive halogen. The order of reactivity is chlorine > bromine > iodine. This is because chlorine could...

2022年12月8日 · The reactivity of halogens is also shown by their displacement reactions with other halide ions in solutions; A more reactive halogen can displace a less reactive halogen from a halide solution of the less reactive halogen; Eg. The addition of chlorine water to a solution of bromine water: Cl 2 (aq) + 2NaBr (aq) → 2NaCl (aq) + Br 2 (aq)

2023年5月18日 · A halogen displacement reaction occurs when a more reactive halogen displaces a less reactive halogen from an aqueous solution of its halide; The reactivity of group 7 elements decreases as you move down the group; You only need to learn the displacement reactions with chlorine, bromine and iodine
Halogen Displacement Reactions | 14–16 Practicals - YouTube
2021年2月22日 · This microscale experiment shows the reactions between chlorine, bromine and iodine ions with potassium chloride, potassium bromide and potassium iodide respectively. You will see a colour change...

When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces bromine...
Displacement – a type of chemical reaction where part of one reactant is replaced with another reactant. The displacement reactions occurring in this practical are single displacement reactions and take the form: AB + C → AC + B Reactivity – a measure of how readily a substance undergoes a chemical reaction.

Halogen displacement reactions - science-revision
Displacement reactions can be carried out using aqueous solutions of the halogens, that is solutions of the halogens dissolved in water. Examples of these displacement reactions are explained in the video opposite.
The Periodic Table: Halogen Displacement Reactions
A Halogen Displacement Reaction involves halogens, the elements found in Group 7 of the Periodic Table. These elements are also known as the halides. They include Fluorine, Chlorine, Bromine, Iodine, and Astatine. A hallmark characteristic of halogens is their reactivity - which decreases as you move down the group from Fluorine to Astatine. In ...
Count the number of reactions seen in each row and write the results in your table – the halogen that produces the most reactions is the most reactive of the three. Write the names of the halogens in order of reactivity, from the most reactive to the least. Compare your reactivity series with group 7 in the periodic table – what do you notice?
