您如何識(shí)別KOH？

How do you identify KOH?

氫氧化鉀，也稱為堿液，是一種無機(jī)化合物，化學(xué)式為KOH。也通常稱為苛性鉀堿，它是一種以各種形式出售的堿，包括顆粒、薄片和粉末。它用于各種化學(xué)、工業(yè)和制造應(yīng)用。天津永達(dá)化學(xué)試劑為您提供多種規(guī)格、濃度的高品質(zhì)氫氧化鉀試劑供您選擇。

Potassium hydroxide, also known as lye, is an inorganic compound with the chemical formula KOH. Also commonly known as caustic soda, it is a powerful alkali sold in various forms, including particles, flakes and powders. It is used in various chemical, industrial and manufacturing applications. Tianjin Yongda chemical reagent provides you with high-quality potassium hydroxide reagents of various specifications and concentrations for your choice.

KOH的酸度是多少？

What is the acidity of KOH?

堿的酸度等于它包含的可替換氫的數(shù)量。KOH中只有一個(gè)氫，所以KOH的酸度為1。

The acidity of a base is equal to the amount of replaceable hydrogen it contains. There is only one hydrogen in KOH, so the acidity of KOH is 1.

KOH易燃嗎？

Is KOH flammable?

氫氧化鉀在潮濕空氣中對(duì)鋁、鋅、錫、鉛等金屬有腐蝕性，形成易燃易爆的氫氣。

Potassium hydroxide is corrosive to aluminum, zinc, tin, lead and other metals in humid air, forming flammable and explosive hydrogen.

KOH是吸濕性的還是潮解性的？

Is KOH hygroscopic or deliquescent?

潮解性物質(zhì)是傾向于從空氣中吸收水分并將其溶解的固體。例如：NaOH、KOH、MgCl2、CaCl2、FeCl3、LiCl、Cu(NO3)2、NaNO3、LiNO3等都是潮解性物質(zhì)。

Deliquescent substances are solids that tend to absorb water from the air and dissolve it. For example, NaOH, Koh, MgCl2, CaCl2, FeCl3, LiCl, Cu (NO3) 2, NaNO3, LiNO3, etc. are deliquescent substances.

KOH中的活性成分是什么？

What are the active ingredients in KOH?

KOH的活性成分是3-(三甲氧基甲硅烷基)丙基二甲基十八烷基氯化銨。為使用，活性成分為總配方的0.75%。非活性成分是純凈水（超過99%的配方）和烷氧基化脂肪醇。

The active component of KOH is 3 - (trimethoxysilyl) propyl dimethyl octadecyl ammonium chloride. For safe use, the active ingredient is 0.75% of the total formula. The inactive ingredients are purified water (more than 99% of the formula) and alkoxylated fatty alcohols.

為什么KOH是堅(jiān)實(shí)的基礎(chǔ)？

Why is KOH a solid foundation?

KOH是強(qiáng)堿，KOH→KOH-，所以在水溶液中完全解離成負(fù)離子（它們是氫氧根離子，OH-）和正離子。pH8.35是高pH(>7)，因此這是一種堿性溶液。

Koh is a strong base, Koh → KOH -, so it is completely dissociated into negative ions (they are hydroxyl ions, oh -) and positive ions in aqueous solution. pH8. 35 is a high pH (> 7), so it is an alkaline solution.

氫氧化鉀(KOH)長什么樣？

What does potassium hydroxide (KOH) look like?

氫氧化鉀又稱苛性鉀、堿液和鉀堿液。這種堿金屬氫氧化物是一種非常強(qiáng)大的堿。在其水性形式中，它具有透明溶液的外觀。在其固體形式中，KOH可以呈白色淡黃色塊狀、薄片、丸狀或棒狀存在。

Potassium hydroxide is also known as caustic potassium, alkali liquor and potassium alkali liquor. This alkali metal hydroxide is a very powerful alkali. In its aqueous form, it has the appearance of a transparent solution. In its solid form, Koh can exist in white to light yellow blocks, flakes, pellets or rods.

KOH存在于哪種晶體結(jié)構(gòu)中？

What kind of crystal structure does KOH exist in?

固體KOH具有菱面體晶體結(jié)構(gòu)，類似于氯化鈉。制備：KOH的工業(yè)制備與NaOH的制備相似，采用氯堿法。

Solid KOH has rhombohedral crystal structure, which is similar to sodium chloride. Preparation: the industrial preparation of KOH is similar to that of NaOH, using chlor alkali method.

化學(xué)式為KOH的無機(jī)化合物是什么？

What is the inorganic compound with chemical formula KOH?

氫氧化鉀是一種無機(jī)化合物，化學(xué)式為KOH，俗稱苛性鉀。與氫氧化鈉(NaOH)一起，這種無色固體通常是強(qiáng)堿。

Potassium hydroxide is an inorganic compound with chemical formula Koh, commonly known as caustic potassium. Together with sodium hydroxide (NaOH), this colorless solid is usually a strong base.

制備KOH用什么試劑？

What reagent is used to prepare KOH?

氫氧化鉀是一種具有強(qiáng)腐蝕性的潮解性化學(xué)品，因此請(qǐng)小心處理，并確保在使用后將化學(xué)品儲(chǔ)存瓶塞緊。使用二甲亞砜-KOH試劑：將二甲亞砜(DMSO)添加到KOH中，可以立即或幾分鐘后檢查樣品。

Potassium hydroxide is a highly corrosive deliquescent chemical, so please handle it carefully and ensure that the chemical storage bottle is tightly plugged after use. Use dimethyl sulfoxide KOH reagent: add dimethyl sulfoxide (DMSO) to KOH and check the sample immediately or after a few minutes.
