在酸价测试中，氢氧化钾也可作为一种主要的原料来辅助测试。作为一种较为常见的化学原料，氢氧化钾有什么性质、状态、功能等常规概况呢？今天我们来了解一下。

Potassium hydroxide can also be used as a main raw material to assist in acid value testing. As a relatively common chemical raw material, what are the general properties, states, and functions of potassium hydroxide? Today, let's take a look.

氢氧化钾除了学名外，还有很多别名，又称苛性钾、苛性碱、钾灰等，它的化学式是KOH，其状态主要是呈白色粉末或片状固体。

In addition to its scientific name, potassium hydroxide also has many aliases, also known as caustic potassium, caustic soda, potassium ash, etc. Its chemical formula is KOH, and its state is mainly in the form of a white powder or sheet solid.

氢氧化钾的熔点是380℃，沸点更是高达1324℃，算是很有“高冷”气质了。氢氧化钾的相对密度是2.04g/cm2。

The melting point of potassium hydroxide is 380 ℃, and the boiling point is as high as 1324 ℃, which is considered a "high cold" temperament. The relative density of potassium hydroxide is 2.04g/cm2.

它具强碱性及腐蚀性，其性质与烧碱相似。它易吸收空气中水分而潮解，吸收二氧化碳而成碳酸钾。当它溶解于水、醇或用酸处理时会产生大量热量。它也会溶于乙醇，微溶于醚。

It is highly alkaline and corrosive, and its properties are similar to those of caustic soda. It easily absorbs moisture in the air and deliquesces, absorbing carbon dioxide to form potassium carbonate. When dissolved in water, alcohol, or acid, it generates a large amount of heat. It is also soluble in ethanol and slightly soluble in ether.

从化学性质方面来看，氢氧化钾0.1mol/L溶液的pH为13.5，并且具有碱的通性，可使石蕊试液变蓝、酚酞试液变红，还可与酸、酸性氧化物、两性金属、两性氧化物、两性氢氧化物等发生化学反应。

From the perspective of chemical properties, the pH of 0.1mol/L potassium hydroxide solution is 13.5, and it has alkali permeability, which can make litmus test solution turn blue and phenolphthalein test solution turn red. It can also undergo chemical reactions with acids, acidic oxides, amphoteric metals, amphoteric oxides, and amphoteric hydroxides.

氢氧化钾的应用领域很广泛：

Potassium hydroxide has a wide range of applications:

其一，它可以运用在干燥剂、吸收剂、制草酸及各种钾盐等方面，还可用于电镀、雕刻、石印术等方面。

First, it can be used in desiccants, absorbents, oxalic acid production, and various potassium salts, as well as in electroplating, sculpture, lithography, and other fields.

其二，它还用作钾盐生产的原料，如高锰酸钾、碳酸钾等。在医药工业中，用于生产钾硼氢、安体舒通、沙肝醇、丙酸睾丸素等。

Secondly, it is also used as a raw material for the production of potassium salts, such as potassium permanganate and potassium carbonate. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, salganol, testosterone propionate, etc.

在轻工业中用于生产钾肥皂、碱性蓄电池、化妆品（如冷霜、雪花膏和洗发膏）。在染料工业中，用于生产还原染料，如还原蓝RSN等。等等。

It is used in the production of potassium soap, alkaline batteries, and cosmetics (such as cold cream, snow cream, and shampoo) in the light industry. In the dye industry, it is used to produce vat dyes such as vat blue RSN. wait.

既然是说氢氧化钾的常识，那么在了解它的应用领域之后，也来了解一下它的另一些方面的常识。

Since this is the common sense of potassium hydroxide, after understanding its application fields, let's also learn about other aspects of it.

例如，它对组织有烧灼作用，可溶解蛋白质，形成碱性变性蛋白质。溶液或粉尘溅到皮肤上，尤其溅到黏膜，可产生软痂。

For example, it has a cauterizing effect on tissues and can dissolve proteins to form alkaline denatured proteins. Solution or dust splashed onto the skin, especially onto the mucous membrane, can produce soft scabs.

溶液浓度越高，温度越高，作用越强。溅入眼内，不仅可损伤角膜，而且能使眼部深组织损伤。

The higher the concentration and temperature of the solution, the stronger the effect. Splash into the eye can not only damage the cornea, but also cause deep tissue damage in the eye.

氢氧化钾的高容许浓度为0.5mg/m，所以在做与其有关的工作时，应防止触及皮肤和眼睛，做好防护，也是对自己和工作的负责。更多产品了解就来我们网站http://www.jinhao360.com咨询！

The high allowable concentration of potassium hydroxide is 0.5 mg/m3, so when doing work related to it, it is necessary to prevent contact with skin and eyes, and take good precautions. It is also responsible for oneself and work. For more product information, please visit our website http://www.jinhao360.com consulting service
