高中化學都是學得各種各樣酸，特別是在區別強堿和弱酸性，強堿對身體的損害十分大，是因為其具備強勁的腐蝕，弱酸性相對而言腐蝕不那麼強，酸值弱才被區別為弱酸性。在其中草酸便是弱酸性中的意味著，很多草里邊都是含有草酸。

High school chemistry is all about learning all kinds of acids, especially in distinguishing between strong bases and weak acids. Strong bases do great damage to the body because they have strong corrosion. Weak acidity is relatively weak, and weak acid value is distinguished as weak acidity. Oxalic acid is weak acidity, which means that many grasses contain oxalic acid.

草酸是生物體的一種代謝產物。草酸廣泛分布于植物、動物和真菌體中，并且在不同的生命體中發揮著不同的功能。其中植物中的草酸成分含量會比較高,比如菠菜、莧菜、甜菜、馬齒莧、芋頭、甘薯和大黃等植物。

Oxalic acid is a metabolite of organism. Oxalic acid is widely distributed in plants, animals and fungi, and plays different functions in different organisms. Among them, the content of oxalic acid in plants will be relatively high, such as spinach, amaranth, beet, purslane, taro, sweet potato, rhubarb and other plants.

草酸能洗廁所。

Oxalic acid can wash the toilet.

草酸的PH值相當高，所以對于清洗污垢等物質具有明顯的作用。但是草酸的酸性過強同時也會對陶瓷表面產生一定的腐蝕性，因此建議在短時間內完成沖洗過程，并且一定要清洗干凈不要讓廁所存有殘留的草酸溶液。

The pH value of oxalic acid is quite high, so it has an obvious effect on cleaning dirt and other substances. However, the strong acidity of oxalic acid will also produce certain corrosivity on the ceramic surface. Therefore, it is recommended to complete the washing process in a short time, and be sure to clean it so that there is no residual oxalic acid solution in the toilet.

清潔馬桶時，先將草酸噴到馬桶的表面，等待1分鐘左右，用擦洗物進行輕輕的擦洗即可。此時可以再噴一次草酸溶液，等待半分鐘左右，再用足量清水沖洗。

When cleaning the toilet, spray oxalic acid on the surface of the toilet first, wait for about 1 minute, and gently scrub it with a scrub. At this time, spray oxalic acid solution again, wait for about half a minute, and then rinse with sufficient water.

草酸主要用作還原劑和漂白劑，用于生產素和冰片等藥物以及提煉稀有金屬的溶劑、染料還原劑、鞣革劑等。

Oxalic acid is mainly used as reductant and bleach, in the production of antibiotics, borneol and other drugs, as well as solvents for refining rare metals, dye reductants, tanning agents, etc.

草酸可用來除銹。

Oxalic acid can be used to remove rust.

不過使用時要小心，草酸對不銹鋼有較強的腐蝕性。濃度高的草酸也容易腐蝕手。皮膚接觸到草酸應盡快用清水清洗。

However, be careful when using it. Oxalic acid has strong corrosivity to stainless steel. Oxalic acid with high concentration is also easy to corrode hands. In case of skin contact with oxalic acid, clean it with clean water as soon as possible.

草酸使用注意

Notes on the use of oxalic acid

氫氧化鉀廠家在此提醒大家，草酸在人體內不易被氧化分解掉，經代謝作用后產生的物質，歸屬于酸性物質，可造成人體內ph酸堿度不平衡，吃得過多還會繼續中毒了。

Potassium hydroxide manufacturers here remind you that oxalic acid is not easy to be oxidized and decomposed in the human body. The substances produced after metabolism belong to acidic substances, which can cause pH pH imbalance in adults. If you eat too much, you will continue to be poisoned.

并且草酸在人體內假如遇到鈣和鋅便轉化成草酸鈣和草酸鋅，不容易消化吸收而排出來身體之外，影響鈣與鋅的消化吸收。

And if oxalic acid meets calcium and zinc in the human body, it will be converted into calcium oxalate and zinc oxalate, which are not easy to digest and absorb, but discharged out of the body, affecting the digestion and absorption of calcium and zinc.

少年兒童成長發育需要很多的鈣和鋅。假如身體欠缺鈣和鋅，不但可造成骨骼、牙發育不全，并且還會繼續影響大腦發育。

Children need a lot of calcium and zinc for growth and development. If the body lacks calcium and zinc, it can not only cause bone and tooth underdevelopment, but also continue to affect brain development.
