相信大家知道氫氧化鉀具有堿的通性，易溶于水，有強烈腐蝕性，溶于水放出大量熱，除此之外大家知道它的通堿
特點(diǎn)還有有哪些呢？接下來(lái)就給大家來(lái)具體講解一下吧。
　　I believe you know that potassium hydroxide is alkali-soluble, soluble in water, strongly corrosive, dissolving in water emits a lot of heat. In addition, you know what other characteristics of potassium hydroxide? Next, I'll give you a detailed explanation.
　　1.堿性反應：可使石蕊試液變藍、酚酞試液變紅。
　　1. Alkaline reaction: It can make litmus test solution blue and phenolphthalein test solution red.
　　2.氫氧化鉀與酸反應：與鹽酸、硫酸、硝酸反應。
　　2. Reaction of potassium hydroxide with acid: reaction with hydrochloric acid, sulfuric acid and nitric acid.
　　KOH+HCl=KCl+H2O2KOH+H2SO4=K2SO4+2H2OKOH+HNO3=KNO3+H2O
　　KOH+HCl=KCl+H2O2KOH+H2SO4=K2SO4+2H2OKOH+HNO3=KNO3+H2O
　　KOH+HCl=KCl+H2O2KOH+H2SO4=K2SO4+2H2OKOH+HNO3=KNO3+H2O
　　KOH+HCl=KCl+H2O2KOH+H2SO4=K2SO4+2H2OKOH+HNO3=KNO3+H2O
　　3.與酸性氧化物反應：與二氧化碳、二氧化硫反應。
　　3. Reaction with acid oxides: Reaction with carbon dioxide and sulfur dioxide.
　　2KOH+CO2=K2CO3+H2O2KOH+SO2=K2SO3+H2O
　　2KOH+CO2=K2CO3+H2O2KOH+SO2=K2SO3+H2O
　　2KOH+CO2=K2CO3+H2O2KOH+SO2=K2SO3+H2O
　　2KOH+CO2=K2CO3+H2O2KOH+SO2=K2SO3+H2O
　　4.與兩性金屬反應：與鋁反應。2Al+2KOH+2H2O=KAlO2+3H2↑
　　4. Reaction with amphoteric metals: Reaction with aluminium. 2Al+2KOH+2H_2O=KAlO_2+3H_2_

　　5.與兩性氧化物反應：與氧化鋁反應。Al2O3+2KOH=2KAlO2+H2O
　　5. Reaction with amphoteric oxides: Reaction with alumina. Al2O3+2KOH=2KAlO2+H2O
　　6.與兩性氫氧化物反應：Al(OH)3+KOH=KAlO2+2H2O
　　6. Reaction with amphoteric hydroxides: Al(OH)3+KOH=KAlO 2+2H 2
　　7.與過(guò)渡元素鹽溶液發(fā)生復分解反應
　　7. Double decomposition reaction with salt solution of transition element
　　CuSO4+KOH=Cu(OH)2↓+K2SO4FeCl3+3KOH=Fe(OH)3↓+3KCl
　　CuSO4+KOH=Cu(OH)2_+K2SO4FeCl3+3KOH=Fe(OH)3_+3KCl
　　CuSO4+KOH=Cu(OH)2:+K2SO4FeCl3+3KOH=Fe(OH)3:+3KCl
　　CuSO4+KOH=Cu(OH)2:+K2SO4FeCl3+3KOH=Fe(OH)3:+3KCl
　　大家在了解了上述關(guān)于氫氧化鉀的通堿特點(diǎn)，另外，由于它對碳水化合物的分解作用，而使其相對于酸腐蝕的危險更加嚴重，所以大家在使用的時(shí)候一定要注意安全，如果大家還想了解更多資訊，請繼續關(guān)注我們吧。
　　In addition, due to its decomposition of carbohydrates, the risk of acid corrosion is more serious. So we must pay attention to safety when using potassium hydroxide. If you want to know more information, please continue to pay attention to us.
