如若你没看过好意思国解放女神像的老相片，你不详合计解放女神像一直王人是绿色的吧。其实，早先的女神像是古铜色的97色姐姐，那她是若何一步一步变成绿色的呢？一说念来了解其中秘籍。

New York's iconic， blue-green statue of liberty wasn't always green. 纽约的记号性蓝绿色解放女神像并不一直王人是绿色的。

When the statue was gifted to the US from France in 1885， she was actually a shiny copper color. 1885年法国把这座女神像送给好意思国时，她实质上是亮闪闪的古铜色。

A new video reveals the chemical reactions involving oxygen and even air pollution that led to her color change from copper to liberty green. 最近有个视频揭示了氧气和空气稠浊是如何与女神像发生化学反馈，把古铜色变成绿色的。

The statue of liberty was a gift from France to the US as a way of commemorating the US's fight for independence， as well as their own aspiration for democracy. 法国将这座解放女神像送给好意思国动作礼物，是为了归来好意思国的孤苦宣战，以及法国我方对民主的渴慕。

A video， published by the American Chemical Society， explains that the 305-foot (93 meter) statue was built over nine years in sections of copper skin on top of an iron skeleton. 由好意思国化学学会发布的这个视频解释了这座破耗九年形成的高达305英尺（93米）的雕像是如安在铁质框架上包上一层铜。

According to the National Park Service， the statue is made of thirty tons of copper - enough to make 435 million pennies. 好意思国国度公园处置局称，解放女神像由30吨铜打造而成，这些铜足以制造4.35亿枚好意思分硬币。

'In her first few decades in the Big Apple， the statue slowly turned from that shiny copper color to a dull brown and the， finally， to the blue-green， or as they'd say back in France， 'verdigris' we see today，' said the video's narrator. 该视频的诠释注解员说：“在解放女神像入驻纽约市的头几十年，女神像逐步地从闪亮的古铜色变成了昏黑的棕色，临了变成了咱们今天看到的蓝绿色，或者法国东说念主所谓的‘铜绿色’。”

When it changed color， some officials suggested restoring her back to her original color， but after the public protested against this decision， she was left the way she is. 解放女神像早先变色时，一些官员提议将其收复成早先的神情，可是公众对这个决定示意抗议，于是女神像的这个神情就保留了下来。

The statue's color change was as a result of oxidation reactions between copper and the air. 解放女神像变色是铜和空气氧化反馈的遵守。

But it was more than one reaction - the color change is due to about 30 years worth of different reactions leading to a mixture of greenish minerals. 可是这种变色不单缘于一种化学反馈，而是三十年间多种不同的化学反馈相搀杂才导致了这种绿色。

Oxidation reactions happen when an atom loses an electron to another atom. 当一个原子的一个电子治愈给了另一个原子，这时就发生了氧化反馈。

In the case of the statue of liberty， her color change was bound to happen due to oxygen in the atmosphere that is 'hungry' for electrons. 解放女神像的神情变化是势必会发生的，因为周围空气中的氧气“渴求”电子。

On top of this， elements of New York City's polluted air added to the color change too. 除此除外，纽约市空气中的稠浊物资也促成了神情的变化。

The first chemical reaction of the color change involved copper giving up electrons to electron-hungry oxygen in the atmosphere. 和神情变化联系的第一个化学反馈是铜将电子治愈给了周围渴求电子的氧气。

This led to a mineral called cuprite - which is pinkish red. 这种化学反馈的遵守是生成一种叫作赤铜矿的矿物资，赤铜矿呈肉红色。

Then， cuprite loses even more electrons to oxygen， forming a new mineral called tenorite， which is blackish in color. 赤铜矿赔本更多电子给氧气，从而形成了名为黑铜矿的新矿物资，黑铜矿神情发黑。

The black color of tenorite explains why the statue got darker over time， forming a dark brown color. 黑铜矿的玄色解释了为什么女神像这些年来神情越来越暗，呈现出深棕色。

Then， further chemical reactions occurred when sulfur in the atmosphere reacts with water. 接下来，当周围空气中的硫与水战斗时，又发生了进一步的化学反馈。

Sulfur comes from natural processes such as volcanic eruptions， but also from man-made emissions from boats， cars， airplanes and factories. 硫来自火山喷发等当然进程，但船舶、汽车、飞机和工场的东说念主为排放也会产生硫。

When sulfur dioxide in the atmosphere reacts with water， it produces sulfuric acid. 当空气中的二氧化硫与水发生反馈时，就会产生硫酸。

Sulfuric acid forms green minerals with copper oxides， so the sulfuric acid in the atmosphere made the state green over time. 硫酸和氧化铜发生反馈，生成了绿色的矿物资，就这么，跟着技艺的荏苒，周围空气中的硫酸将解放女神像变成了绿色。

Added to that， chloride from the sea spray surrounding Ellis Island where the statue is located made the statue even greener. 此外，解放女神像所在的埃利斯岛四周海潮中的氯化物让女神像的神情变得更绿。

The statue stayed this way for over 100 years because the exposed copper is now oxidized and stable， but the statue wouldn't be the same anywhere else. 解放女神像就这么保合手了100多年，因为表示在空气中的铜仍是被氧化，化学性质踏实下来，但这尊女神像如若放在其他任何场地王人不会是这个神情。
