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.

　　比擬簡單的是量取體積一定的KOH溶液，滴入幾滴酚酞指示劑（變紅），然后用濃度一定的酸性物質，譬如HCL,裝入酸式滴定管，滴定到KOH溶液紅色根本褪去（未完整褪去），此時搖勻杯子，主要是避免溶液擴散不平均，然后繼續滴定紅色消逝，滴定過程中眼睛要留意杯子中顏色變化，及時關掉滴定管。記下HCL耗費的體積，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).

　　氫氧化鉀的性質較好，在產品應用方面，由于性質較多，在很多方面和檢驗實驗方面都有著很好的應用，下面這篇文章為大家細致解說這種物質的溶液的霉菌檢查法，大家一同來理解一下吧。

　　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.用灑桔棉球撩凈皮損。

　　1. Use orange cotton balls to clean the skin.

　　2.以一枚玻璃片邊緣刮取皮權的顯著部位，翌殘屑或殘物于另一玻璃承物。

　　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處，（2）趾間發軟或有分泌物的部位，（3）損傷的邊繳，（4）拔發的基部。

　　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.運用10％的氫氧化鉀1滴與承物片上的殘屑或殘物混勻。

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

　　4.栓綏fm執。臺取招分澆臘（因油臘易析出氫氧化鉀結晶），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倍鏡頭，在低照明度下停止觀氟。

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

　　6.利的物員少，常常效果更好。

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

　　7.氫氧化鉀可溶解表皮蛋白，但不毀壞霉菌成分時分霉菌不彌散，堅持在角質層細胞膜之間。

　　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.

　　綜上所述，文中解說的七點就是氫氧化鉀溶液的霉菌檢查法，大家在應用這種產品的時分，假如想要檢查這種產品的性質，能夠應用這種辦法，希望文中解說的內容對大家有協助作用。

　　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.
