Potassium bromide is not acutely toxic and it poses a low toxicity hazard. Its oral toxicity is well known and is very low. A high dose will cause only nausea and vomiting. Similarly, its dermal toxicity is low, and it is not a skin irritant.

kbr acid or base

KBR, or potassium bromide, is an ionic compound that consists of the potassium cation (K+) and the bromide anion (Br-). In its solid form, KBR is a white crystalline substance. When KBR is dissolved in water, it dissociates into its constituent ions, resulting in a solution that can exhibit both acidic and basic properties.

KBR itself is a neutral compound since it does not contain any hydrogen ions (H+) or hydroxide ions (OH-). However, when KBR is dissolved in water, the bromide ions (Br-) can interact with water molecules to form hydrobromic acid (HBr) and hydroxide ions (OH-):

Br- + H2O → HBr + OH-

In this reaction, the formation of HBr results in the release of hydrogen ions (H+), which makes the solution acidic. On the other hand, the hydroxide ions (OH-) formed can contribute to the basicity of the solution.

Therefore, the aqueous solution of KBR can be considered as slightly acidic due to the presence of hydrobromic acid (HBr) formed from the dissociation of bromide ions. However, the acidity or basicity of the solution will depend on the concentration of KBR and the specific conditions of the solution.

what is potassium bromide

Potassium bromide (KBr) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US. Its action is due to the bromide ion (sodium bromide is equally effective).

potassium bromide uses

Potassium bromide was used as a secondary halide in combination with an iodide in the paper negative processes, the albumen on glass process, and the wet collodion processes. When silver bromide gelatin emulsion was invented, potassium bromide was the primary halide. It was also used in combination with either bichloride of mercury, copper sulfate, or potassium ferricyanide in photographic bleaches and as a restrainer in alkaline developers used for gelatin plates and developing-out papers.

is kbr soluble in water

Potassium bromide is highly soluble in water. The solubility of potassium bromide in water is 687 g/L at 25°C.
