Physical and Chemical Properties | Physicochemical properties Silver bromide is a colorless tetragonal crystal. Toxic! Relative density 5.206. Silver bromide is easily soluble in ammonia, slightly soluble in water and nitric acid. When heated, it decomposes, releases oxygen, and becomes silver bromide. Pure products are stable to light and do not decompose even when boiled with water, but are easily reduced by organic matter. |
Use | Uses Silver bromate is commonly used as an oxidizing agent. |

introduction
Silver bromide is the bromate of silver, the chemical formula is AgBrO3. Silver bromide is usually used as an oxidant.
Preparation
Like silver chloride, the most commonly used preparation method for silver bromide is to react with hydrobromic acid or alkali metal bromide and silver nitrate to obtain: M = H, alkali metal,
Silver bromide also exists in nature in the form of silver bromide.
Solubility in water (g/100ml)
Dissolved grams per 100 ml of water at different temperatures (℃):
0.11g/10℃;0.16g/20℃;0.23g/30℃;0.32g/40℃
0.57g/60℃;0.94g/80℃;1.33g/90℃
production method
Soluble bromate reacts with silver sulfate (I) to produce silver bromate.
