请帮帮翻译一段长话hydrogen peroxide in sodium percar ...? also the active oxygen concentration from hydrogen peroxide in sodium percarbonate can be obtained and accurate volumetric analysis of hydrogen peroxide by reducing ceric salts to cerous salts or by liberating iodine from an iodide, followed by titration with a thiosulfate solution . 俺的无机化学忘得差不多啦,先帮俺搞清楚氧化反应和还原反应吧。 反应1--- reducing ceric salts to cerous salts----4价铈盐变成3价铈-----还原反应 反应2.---liberating iodine from an iodide-----碘化物变成碘------氧化反应 所以俺想应该是 用反应1来测定过氧化氢; 用反应2来测定过氧化氢生成的活性氧。查看更多
