高中化学都是学得各种各样酸，特别是在区别强碱和弱酸性，强碱对身体的损害十分大，是因为其具备强劲的腐蚀，弱酸性相对而言腐蚀不那麽强，酸值弱才被区别为弱酸性。在其中草酸便是弱酸性中的意味着，很多草里边都是含有草酸。
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.
草酸是生物体的一种代谢产物。草酸广泛分布于植物、动物和真菌体中，并且在不同的生命体中发挥着不同的功能。其中植物中的草酸成分含量会比较高,比如菠菜、苋菜、甜菜、马齿苋、芋头、甘薯和大黄等植物。
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.
草酸能洗厕所。
Oxalic acid can wash the toilet.
草酸的PH值相当高，所以对于清洗污垢等物质具有明显的作用。但是草酸的酸性过强同时也会对陶瓷表面产生一定的腐蚀性，因此建议在短时间内完成冲洗过程，并且一定要清洗干净不要让厕所存有残留的草酸溶液。
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.
清洁马桶时，先将草酸喷到马桶的表面，等待1分钟左右，用擦洗物进行轻轻的擦洗即可。此时可以再喷一次草酸溶液，等待半分钟左右，再用足量清水冲洗。
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.
草酸主要用作还原剂和漂白剂，用于生产抗菌素和冰片等药物以及提炼稀有金属的溶剂、染料还原剂、鞣革剂等。
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.

草酸可用来除锈。
Oxalic acid can be used to remove rust.
不过使用时要小心，草酸对不锈钢有较强的腐蚀性。浓度高的草酸也容易腐蚀手。皮肤接触到草酸应尽快用清水清洗。
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
氢氧化钾厂家在此提醒大家，草酸在人体内不易被氧化分解掉，经代谢作用后产生的物质，归属于酸性物质，可造成人体内ph酸碱度不平衡，吃得过多还会继续中毒了。
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.
并且草酸在人体内假如遇到钙和锌便转化成草酸钙和草酸锌，不容易消化吸收而排出来身体之外，影响钙与锌的消化吸收。
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.
少年儿童成长发育需要很多的钙和锌。假如身体欠缺钙和锌，不但可造成骨骼、牙发育不全，并且还会继续影响大脑发育。
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.
