2023年6月30日 · All the halogens react directly with hydrogen, forming covalent bonds and—at sufficient levels of purity—colorless gases at room temperature. Hydrogen reacts with fluorine, chlorine, bromine, and iodine, forming HF, HCl, HBr, and HI, respectively.

2023年6月30日 · Group 17: Halogens. Generally halogens react with water to give their halides and hypohalides. The halogen gases vary in their reactions with water due to their different electronegativities. Because fluorine (\(\ce{F2}\)) is so electronegative, it can …

Halogens react to a small extent with water, forming acidic solutions with bleaching properties. They also undergo redox reactions with metal halides in solution, displacing less reactive halogens from their compounds.

When halogens react with water, they form halogenated water and halogen acids. However, the reactivity of halogens with water varies among the different halogens. Fluorine is the most reactive of the halogens and reacts explosively with water to form hydrogen fluoride (HF) and oxygen.

2025年1月3日 · Halogen Displacement Reactions. 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:

Thereby, hydrogen can readily bond to fluorine forming HF molecules, facilitating displacement of oxygen as the element. We cannot form HCl and heavier congener molecules so easily in water, so we don't break all the original bonds between hydrogen and oxygen and thus we get products with hydroxyl groups like HOCl.

2012年4月8日 · Chlorine, bromine and iodine are soluble in water to form an acidic solution. The solubility decreases down the group. Aqueous chlorine and bromine are a bleaching agent. Aqueous iodine does not act as a bleaching agent. Chlorine gas is produced through the following reaction: 2KMnO 4 + 16HCl → 2KCl + 2MnCl 2 + 5Cl 2 + 8H 2 O

2023年7月12日 · In 1774, Carl Wilhelm Scheele (the codiscoverer of oxygen) produced chlorine by reacting hydrochloric acid with manganese dioxide. Scheele was convinced, however, that the pale green gas he collected over water was a compound of oxygen and hydrochloric acid.

have shown a darker, red/orange/brown colour yet it was a light orange. This colour is more intense than that of chlorine’s as it is more soluble but it should be darker than the observation – this coul. The chlorine solution was pale green, the …

Yes, halogens are reactive with water. Fluorine (F), Chlorine (Cl), Bromine (Br) and Iodine (I) are the elements of the halogen family. They belong to the 17 t h group in the periodic table on the right-hand side. Their reactivity decreases as we move down the group.
