Reaction of bromine and chlorine with phenolic

The rate for the reactions of chlorine and bromine with phenolic compounds is pH-dependent due to the differences in reactivity of the hypohalous acid and the hypohalite anion and the higher reactivity of the phenolate compared to the phenol (Rebenne et al., 1996, Gallard and von Gunten, 2002, Deborde and von Gunten, 2008, …

Q9: What are the chlorine and bromine reactions that destroy

The most reactive of these gases are chlorine monoxide (ClO), bromine monoxide (BrO), and chlorine and bromine atoms (Cl and Br). These gases participate in three prin-cipal reaction cycles that destroy ozone. Cycle 1. Ozone destruction Cycle 1 is illustrated in Figure Q9-1. The cycle is made up of two basic reac-tions: ClO + O and Cl + O 3 ...

The Chemistry of the Halogens

Discussions of the chemistry of the elements in Group VIIA therefore focus on four elements: fluorine, chlorine, bromine, and iodine. These elements are called the halogens (from the Greek hals, "salt," and gennan, "to form or generate") because they are literally the salt formers. None of the halogens can be found in nature in their elemental ...

Chlorine vs. Bromine: What's the Difference?

Chlorine and bromine are sanitizers that help keep your pool or spa water clean and safe. Both chlorine and bromine come in tablet and granular form, while chlorine is also available in liquid form. Understanding how each sanitizer works is key to deciding which one is the best option for your pool or spa.

Group 17: General Properties of Halogens

Chlorine reacts with metals to produce salts called chlorides. Chloride ions are the most abundant ions that dissolve in the ocean. Chlorine also has two isotopes: 35 Cl and 37 Cl. Sodium chloride is the most prevalent compound of the chlorides. Bromine - Bromine has an atomic number of 35 with a symbol of Br. It was first discovered in 1826.

Halogens as Oxidizing Agents

Chlorine, Bromine and Iodine. In each case, a halogen higher in the group can oxidize the ions of one lower down. For example, chlorine can oxidize bromide ions to bromine: Cl2 + 2Br− → 2Cl− +Br2 Cl 2 + 2 Br − → 2 Cl − + Br 2. The bromine forms an orange solution. As shown below, chlorine can also oxidize iodide ions to iodine:

More Reactions of Halogens

All halogens react with sodium to produce sodium halides. A common reaction between hot sodium and chlorine gas produces a bright orange flame and white sodium chloride. 2Na + Cl2 → 2NaCl 2 N a + C l 2 → 2 N a C l. Hot sodium will also burn in bromine or iodine vapor to produce sodium bromide or sodium iodide.

Bromine Vs. Chlorine: What's The Difference?

3. Chlorine is Cheaper to Use. Chlorine is almost always cheaper than bromine, which means it's cheaper to use as a residual sanitizer. Bromine tends to be more expensive than chlorine because it's not as widely produced or sold, and a lesser demand for the product inherently increases manufacturing costs.
