氫氧化鉀外觀為白色片狀或粉狀，具有強烈腐蝕性和強堿性。氫氧化鉀溶液外觀則為無色透明狀溶液。氫氧化鉀暴露在空氣中時，易被空氣中的水分而潮解，并吸收二氧化碳而成碳酸鉀。

Potassium hydroxide appears as a white flake or powder, with strong corrosiveness and alkalinity. The appearance of potassium hydroxide solution is colorless and transparent. When potassium hydroxide is exposed to the air, it is easily deliquescent by the moisture in the air and absorbs carbon dioxide to form potassium carbonate.

氫氧化鉀易溶于水、乙醇或酸時，會釋放大量的熱量。氫氧化鉀溶液化學式為KOH，分子量為56.1，沸點為1324℃，熔點為360.4℃，相對密度(水=1)為2.04。0.1mol/L溶液的pH為13.5。

When potassium hydroxide is easily soluble in water, ethanol, or acid, it releases a large amount of heat. The chemical formula of potassium hydroxide solution is KOH, with a molecular weight of 56.1, a boiling point of 1324 ℃, a melting point of 360.4 ℃, and a relative density (water=1) of 2.04. The pH of 0.1mol/L solution is 13.5.

氫氧化鉀主要被用于干燥劑、吸收劑。還用于電鍍、雕刻、石印術等。在紡織工業中，用于印染和漂白作用，并大量用作制造人造纖維、聚酯纖維的主要原料。

Potassium hydroxide is mainly used as a desiccant and absorbent. It is also used for electroplating, carving, lithography, etc. In the textile industry, it is used for printing, dyeing, and bleaching, and is widely used as the main raw material for manufacturing artificial fibers and polyester fibers.

氫氧化鈉俗稱片堿，外觀為白色半透明狀的固體，具有強腐蝕性的強堿。氫氧化鈉溶于水時會形成堿性溶液，其水溶液沒有吸水性，但能與酸發生反應并放熱，可能會產生有毒性煙霧。

Sodium hydroxide, commonly known as flake alkali, is a white semi transparent solid with strong corrosiveness. When sodium hydroxide is dissolved in water, it forms an alkaline solution. Its aqueous solution does not absorb water, but it can react with acids and release heat, which may produce toxic smoke.

氫氧化鈉相對密度2.130；熔點318.4℃；沸點1390℃。氫氧化鈉的質量標準分別有含量為99片堿和96片堿。

Sodium hydroxide relative density 2.130; Melting point 318.4 ℃; Boiling point 1390 ℃. The quality standards for sodium hydroxide are 99 tablets of alkali and 96 tablets of alkali, respectively.

氫氧化鈉廣泛用于粘膠纖維、人造絲及綿織品等輕紡工業方面，農藥、染料、橡膠和化學工業方面、石油鉆探，精煉石油油脂和提煉焦油的石油工業。

Sodium hydroxide is widely used in light textile industries such as viscose fibers, rayon, and cotton fabrics, as well as in the fields of pesticides, dyes, rubber, and chemical industries, petroleum drilling, refining of petroleum oils, and refining of tar in the petroleum industry.

氫氧化鉀溶液的吸濕性比氫氧化鈉強，所以常用氫氧化鉀做干燥劑。更多相關事項就來我們網站http://www.ileleli.cn咨詢吧！
