The Rio Olympics "Green pools" mystery solved: you accidentally added hydrogen peroxide-the Rio Olympics, Olympics-IT information

Local time on August 10, Australia and Japan are ready to start the men's water polo, but interesting, is the screen left of the diving pool, the pool of water overnight turned from blue to green, with the right side of the picture in stark contrast to the venue for water polo in the pool.

August 14, according to foreign media reports, the Rio Olympic diving pool turned green for several days, the answer finally solved! Brazil said that cleaning the pool with the hydrogen peroxide (hydrogen peroxide), but mixed with chlorine use, two chemicals that neutralize chlorine in the water was, floating algae flourish, will make pool water turn green.

Officials insisted on green water is harmless, but for the sake of convenience since then involved in synchronized swimming athletes and referees, decided in Brazil 13th for the competition pool with water, and then back into the up to 1 million gallons of water.

However, in the synchronized swimming pool next door diving pool, will continue for the rest of the game continued to use nontoxic "green water", and will only replace the water filter, and waiting for the water to become clear.

However, the United States media views of chemists. Experts point out that this interpretation is not to believe, because unless the two synthetic hydrochloric acid, chemicals, water is not green. Experts also pointed out that the hydrogen peroxide and chlorine gas are likely to be the cause of pool water is not clean, but unstable and decomposition of hydrogen peroxide, only possibility.

里约奥运会“碧池”之谜终解开：不小心误加双氧水 - 里约奥运会,奥运会 - IT资讯

当地时间8月10日，澳大利亚与日本队的男子水球项目准备开始，但引人关注的，是画面左侧的跳水池，该池子里的水一夜之间从蓝色变成了绿色，与画面右侧的水球场地中的池水形成了鲜明对比。

8月14日据外媒报道，里约奥运跳水池变绿多日，谜底终于解开！巴西工作表示，在清洗水池时用了过氧化氢（即双氧水），但错误与氯混合使用，两种化学物质产生作用让水中氯气被中和，浮藻得以滋生，才会令池水变绿。

有官员坚持绿水无害，但为求方便此后参与花样游泳的选手及裁判，所以决定在巴西时间13日为比赛池放水，然后再重新注入多达100万加仑清水。

不过，在花样游泳比赛池隔壁的跳水池，则会继续在余下的比赛中继续使用无毒“绿水”，且只会更换滤水器，并等待池水变得清澈。

不过，也有美国媒体采访化学家的意见。专家指出，这种解释不可尽信，因为除非两种化学物合成氢氯酸，水是不会这样变绿。专家还指出，过氧化氢及氯气有可能是池水不干净的成因，但过氧化氢不稳定及分解快，所以只是有这样的可能性。
