①能使無色酚酞試液變紅色，能使紫色石蕊試液變藍(lán)色，能使?jié)駶櫦t色石蕊試紙變藍(lán)。實驗室中常見此法檢驗NH3的存在。 ②能與酸反應(yīng)，生成銨鹽。濃氨水與揮發(fā)性酸(如濃鹽酸和濃硝酸)相遇會產(chǎn)生白煙。 NH3+HCl=NH4Cl (白煙) NH3+HNO3=NH4NO3 (白煙)而遇不揮發(fā)性酸(如硫酸、磷酸)無此現(xiàn)象。實驗室中可用此法檢驗NH3或氨水的存在。工業(yè)上，利用氨水的弱堿性來吸收硫酸工業(yè)尾氣，防止污染環(huán)境。 SO2+2NH3·H2O=(NH4)2SO3+H2O(NH4)2SO3+SO2+H2O=2NH4HSO3 5)沉淀性：氨水是很好的沉淀劑，它能與多種金屬離子反應(yīng)，生成難溶性弱堿或兩性氫氧化物。你想選化工原料?選對合作伙伴很重要,貴陽用戶趁早！貴州元明粉化工原料現(xiàn)貨</p><p style="text-indent:25px">貴陽用戶!高純度的質(zhì)量化工原料報價,廠家直銷！貴州元明粉化工原料現(xiàn)貨</p><p> <p> 氨水 </p> <p> 分子式：NH4OH 分子量：bai35.045 氨水是氨溶于水得到的水溶液du。它是zhi一種重要的化工原料，也是化學(xué)實驗中dao常用的試劑. 氨水(AQUA AMMONIAE) 為一無色透明的液體,具有特殊的強烈刺激性臭味,正因為它具有局部強烈興奮的作用,因此將特定濃度的氨水,直接接觸皮膚會使皮膚變紅,并有灼熱感,因此小心. 氨氣是化肥工業(yè)的中間產(chǎn)品，易溶于水而生成氨水，呈堿性。由于氨水可以作為肥料直接施于農(nóng)田，所以在農(nóng)村使用很普遍。在氨水分裝、運輸和使用過程中，常有不慎濺入眼睛的事故發(fā)生。當(dāng)眼部被氨水灼傷后，如不采取急救措施，可造成角膜潰瘍、穿孔，并進一步引起眼內(nèi)炎癥，**終導(dǎo)致眼球萎縮而失明。氨水在低溫時可析出一水合氨晶體，它的熔點為-79℃，因此NH3·H2O是氨存在于水溶液的主要成分。氨水中也有很小一部分一水合氨發(fā)生電離，
