Due to the different requirements of the manufacturers and the different application environment, the requirements for the concentration of potassium hydroxide are also different, so we need to check whether the concentration of potassium hydroxide meets our requirements before using it, and then let the potassium hydroxide manufacturers introduce its concentration detection methods for you.

　　比拟简单的是量取体积一定的KOH溶液，滴入几滴酚酞指示剂（变红），然后用浓度一定的酸性物质，譬如HCL,装入酸式滴定管，滴定到KOH溶液红色根本褪去（未完整褪去），此时摇匀杯子，主要是避免溶液扩散不平均，然后继续滴定红色消逝，滴定过程中眼睛要留意杯子中颜色变化，及时关掉滴定管。记下HCL耗费的体积，然后公式 C（KOH）=C（HCL）V（HCL）/V（KOH）即可算出。

　　Simple comparison is to take a certain volume of KOH solution, drop a few drops of phenolphthalein indicator (red), and then use a certain concentration of acidic substances, such as HCL, into the acid burette, titration to KOH solution red fade (not completely faded), shake the cup at this time, mainly to avoid the uneven diffusion of the solution, and then continue titration to red fade, the eyes to stay in the titration process. Change the color in the Italian cup. Turn off the burette in time. Write down the volume of HCL consumption, and then calculate the formula C (KOH) = C (HCL) V (HCL) / V (KOH).

　　氢氧化钾的性质较好，在产品应用方面，由于性质较多，在很多方面和检验实验方面都有着很好的应用，下面这篇文章为大家细致解说这种物质的溶液的霉菌检查法，大家一同来理解一下吧。

　　Potassium hydroxide has good properties. In product application, because of its many properties, it has a good application in many aspects and test experiments. The following article will explain the fungus test method for this substance solution in detail. Let's understand it together.

　　1.用洒桔棉球撩净皮损。

　　1. Use orange cotton balls to clean the skin.

　　2.以一枚玻璃片边缘刮取皮权的显着部位，翌残屑或残物于另一玻璃承物。

　　2. Scrape the significant part of the skin right at the edge of one glass sheet, leaving debris or debris on another glass carrier.

　　好的取材部位是：（1）疤疹根部里面或基底处，（2）趾间发软或有分泌物的部位，（3）损伤的边缴，（4）拔发的基部。

　　Good sampling sites are: (1) inside or basal part of scar root, (2) soft or secretory part between toes, (3) side payment of injury, (4) basal part of hair pullout.

　　3.运用10％的氢氧化钾1滴与承物片上的残屑或残物混匀。

　　3. Mix 1 drop of 10% potassium hydroxide with debris or debris on the carrier sheet.

　　4.栓绥fm执。台取招分浇腊（因油腊易析出氢氧化钾结晶），使其固定。

　　4. Shuan Sui fm. The wax is watered separately (because the oil wax is easy to precipitate potassium hydroxide crystallization) to make it fixed.

　　5.用10倍和40倍镜头，在低照明度下停止观氟。

　　5. Stop viewing fluorine at low illumination with 10-fold and 40-fold lenses.

　　6.利的物员少，常常效果更好。

　　6. The effect is often better when there are fewer staffs.

　　7.氢氧化钾可溶解表皮蛋白，但不毁坏霉菌成分时分霉菌不弥散，坚持在角质层细胞膜之间。

　　7. Potassium hydroxide dissolves epidermal proteins, but does not destroy the components of fungi. When the fungi do not disperse, they adhere to the membrane of keratinocytes.

　　综上所述，文中解说的七点就是氢氧化钾溶液的霉菌检查法，大家在应用这种产品的时分，假如想要检查这种产品的性质，能够应用这种办法，希望文中解说的内容对大家有协助作用。

　　To sum up, the seven points explained in this paper are the fungus inspection method of potassium hydroxide solution. When you apply this product, if you want to check the nature of this product, you can apply this method. I hope the contents of the explanation in this paper can help you.
