H2O2 Uses and Benefits

謎と真実のアーカイブ on Instagram: "過酸化水素(H₂O₂)は、 有機汚れの除去によく使われる 強い酸化剤だ。 血液やタンパク質、脂質のような 有機物に触れると、 カタラーゼなどの酵素の働きによって 素早く分解される。 その反応の結果、 生じるのは—— 水(H₂O)と酸素(O₂)。 このとき放出される酸素は、 細かな泡となって繊維の奥に入り込み、 シミの粒子を物理的に押し上げる。 同時に、 酸化反応によって 色の原因となる分子が分解されていく。 過酸化水素をかけると すぐに泡が立ち、 シミが薄くなっていくのはそのためだ。 家庭用として販売されている 約3%濃度の過酸化水素は、 日常使用に適した穏やかな反応性を持つ。 原理はシンプル。 酸素が速く放出されるほど、 有機分子は速く分解される。 過酸化水素は、 洗浄の中でも もっとも直感的に 化学反応を観察できる物質の一つだ。 保存して、 鼻血をよく出す友だちに そっと共有してあげよう。 ——————————————————————— まだ知らなかった様々な興味深い真実を知りたいのなら、 @interesting_fact.zi
