臭素酸銀(I)（しゅうそさんぎんいち、英: silver(I) bromate）は銀の臭素酸塩で、化学式 AgBrO₃ で表される無機化合物。光や熱に敏感な白色粉末で、ハロゲン化安息香酸類製造時の触媒^[2]や、銀系抗菌剤^[3]などとして用いられる。

生成

硝酸銀(I)など水溶性の銀化合物水溶液に、臭素酸カリウム水溶液を加えると沈殿する^[4]。

{\ce {Ag^+(aq)\ + BrO3^-(aq) -> AgBrO3}}

熱水に溶解して冷却することにより再結晶する。

性質

無色の結晶または白色粉末であり、固体は正方晶系に属し、その格子定数はa = 8.59 Å, c = 8.01 Åである^[4]。

水に難溶性で、その溶解度積は以下の通りである^[5]。

{\ce {AgBrO3\ \rightleftarrows \ Ag^{+}(aq)\ +BrO3^{-}(aq)\ ,}}

K_{\rm {sp}}=5\times 10^{-5}

純粋な結晶は光に対し安定であるが、少量の有機物が存在すると還元されて黒色を帯びる。また加熱により分解して酸素を放出し、臭化銀(I)となる。

{\ce {2 AgBrO3 -> 2AgBr\ + 3O2}}
