Most people know that water is made of hydrogen and oxygen. The chemical symbol is H2O, which means that every water molecule consists of two hydrogen atoms bound to one oxygen atom. But did you know that it’s possible to separate water into oxygen and hydrogen? In fact the experiment is so simple that you can do it at home with everyday household equipment.
大部分的人都知道水是由氫和氧所組成，其化學符號是H2O，意思就是每個水分子是由兩個氫原子和一個氧原子結合而成。但你知道水可以分解為氫和氧嗎？事實上，這個實驗簡單到在家中利用家庭日常用品就可以進行。
What you will need: a nine volt battery, two pencils, a piece of cardboard, a glass of warm water, some salt and about 50cm of wire.
實驗所需：一個九伏特的電池、兩枝鉛筆、一張厚紙板、一杯溫開水、一些鹽和約五十公分長的電線。
METHOD- OLOGY
Step 1: Remove the eraser and metal from the ends of the pencils and sharpen at both ends.
Step 2: Push the pencils through the cardboard, about 2cm apart and stand them up in the water.
Step 3: Sprinkle some salt in the water and let it dissolve.
Step 4: Connect a wire from the negative terminal of the battery to the graphite tip of one of the pencils. Connect the other wire from the other pencil to the positive terminal. Observe what happens.
方法
步驟一：取下兩枝鉛筆尾端的橡皮擦和金屬片後，將兩端都削尖。
步驟二：將兩枝鉛筆間隔約兩公分戳入紙板後，使其站立於溫水杯中。
步驟三：在水裡撒一些鹽，待其溶解。
步驟四：將電線的一端接在電池的負極上，另一端連到其中一枝鉛筆的筆芯上。將另一根電線的一頭接上另一枝鉛筆，另一頭連上電池的正極。觀察有什麼變化。
WHY IT WORKS 實驗原理
Hydrogen forms at the cathode (the negative terminal) and chlorine forms at the anode (the positive terminal) in a process known as electrolysis.
Perhaps you’re wondering how you managed to make chlorine from hydrogen and oxygen. The reason is because of the salt. In step three we added salt because electrolysis of pure water is extremely slow. The chemical formula for salt is sodium chloride (NaCl). During electrolysis, the oxygen atoms react with the salt to form chlorine gas.

電池陰極（負極）會產生氫氣，而陽極（正極）則會產生氯氣，這就是所謂的電解作用。
也死你會好奇氯是怎麼從氫和氧中跑出來的。答案就是鹽！在步驟三中，我們加入了鹽，這是因為純水的電解過程極為緩慢，而鹽的化學式是氯化鈉（NaCl）。在電解過程中，氧原子和鹽起作用產生了氯氣。

Electrolysis has many industrial uses, including the production of aluminum, magnesium, and of course chlorine.
電解作用可以應用在許多工業用途上，包括鋁、鎂，當然還有氯的製作。
Scientists have made a groundbreaking discovery in the depths of the Pacific Ocean: oxygen production without the involvement of living organisms. Four kilometers below the surface where sunlight cannot reach, researchers have found metallic lumps generating what they term “dark oxygen.” This form of oxygen is produced through a process independent of photosynthesis. Unlike the traditional photosynthesis process, where organisms use sunlight, carbon dioxide, and water to create energy and oxygen, the newly discovered phenomenon operates in complete darkness. The accidental finding occurred during a study of metal-rich lumps in an abyssal plain between Hawaii and Mexico. These lumps, known as
A: In addition to “Inside Out 2” at the top, what were the other highest-grossing films domestically last year? B: “Gatao: Like Father, Like Son” was the only Taiwanese movie among the top 10 blockbusters, which included five animated films. A: I’m surprised that the Taiwanese hit “The Pig, the Snake and the Pigeon” wasn’t on the chart. B: But it grossed over 500 million Chinese yuan in China, which is nearly NT$2.5 billion. The figure was five times higher than that of the best-selling film in Taiwan. A: Its success shows that Taiwanese movies should go international. A:
A Cameroon-flagged cargo vessel “Shunxin-39” was believed to have caused damage to an undersea cable of Taiwan telecoms operator Chunghwa Telecom on the morning of Jan. 3. It was suspected that the Chinese merchant ship, which was registered with the nationality of another country, deliberately cut off the cable by dragging the anchor over it. While the incident is still under investigation, China has a long history of using maritime tactics to sabotage Taiwan’s infrastructure. In February last year, two cables linking Taiwan to its outlying Matsu Islands were damaged within days of each other by a Chinese fishing
Continued from yesterday（延續自昨日） https://www.taipeitimes.com/News/lang Using a device to isolate a section of the seafloor, the researchers aimed to measure oxygen levels in the enclosed water. Normally, oxygen rates would decrease as marine organisms consume it, but the result was contrary to expectations. The unexpected outcome prompted the team to further investigate the phenomenon. Researchers found the lumps emitted an electric charge similar to that of a AA battery. This charge is believed to trigger a process that splits seawater into hydrogen and oxygen, accounting for the increase. Traditional perspectives propose that oxygen production began around three billion years ago through photosynthesis by ancient
