bromide ion concentration


Bromide Electrode, Bromide ISE, Bromide Ion Selective ...

The Bromide Ion-Selective Electrode has a solid-state crystal membrane. The electrode is designed for the detection of bromide ions (Br- ) in aqueous solutions and is suitable for use in both field and laboratory applications. The Bromide Ion is a monovalent anion. One mole of ( Br-) has a mass of 79.904 grams; 1000ppm is 0.0125M.

Bromate in Drinking-water - WHO

Bromate may be formed in water during ozonation when the bromide ion is present (Haag & Hoigné, 1983). Under certain conditions, bromate may also be formed in concentrated hypochlorite solutions used to disinfect drinking-water (IPCS, 2000). This reaction is due to the presence of bromide in the raw materials (chlorine and

Bromide - Wikipedia

A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. In contrast to chlorides, bromides have relatively few biological or practical roles. Although uncommon, chronic toxicity from bromide can result in bromism, a syndrome with multiple neurological symptoms.

Bromate in Drinking Water - Information Fact Sheet

Bromate is formed when ozone used to disinfect drinking water reacts with naturally occurring bromide found in source water. Bromate formation in disinfected drinking water is influenced by factors such as bromide ion concentration, pH of the source water, the amount of ozone and the reaction time used to disinfect the water.

BROMIDE CONCENTRATIONS IN SURFACE DRINKING WATER …

Source water bromide concentration is one of the most important DBP formation factors and elevated bromide can lead to as much as a two-fold increase in both regulated and unregulated DBPs (Hua et al. 2006, Sfynia 2017). Short-term exposure to high levels of DBPs has been weakly associated with restricted fetal growth

How do you calculate concentration of ions in a solution ...

The concentration of ions in solution depends on the mole ratio between the dissolved substance and the cations and anions it forms in solution. So, if you have a compound that dissociates into cations and anions, the minimum concentration of each of those two products will be equal to the concentration of the original compound. Here's how that works: NaCl_((aq)) -> Na_((aq))^(+) + …
