硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)的(de)(de)主要(yao)用(yong)(yong)(yong)(yong)途有哪些：農業領(ling)域：是(shi)常見的(de)(de)氮肥(fei)，適用(yong)(yong)(yong)(yong)于(yu)一般土壤(rang)和作(zuo)(zuo)物(wu)(wu)，硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)結晶(jing)，能(neng)使枝(zhi)葉(xie)生長旺盛，提(ti)高果實(shi)品(pin)質(zhi)和產量，增強作(zuo)(zuo)物(wu)(wu)對災害的(de)(de)抵抗能(neng)力(li)，可作(zuo)(zuo)基肥(fei)、追(zhui)肥(fei)和種肥(fei)，但長期使用(yong)(yong)(yong)(yong)可能(neng)導致土壤(rang)板結。工業領(ling)域：用(yong)(yong)(yong)(yong)于(yu)制備硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)肥(fei)料、硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)磷肥(fei)、硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)鉀(jia)肥(fei)和硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)鎂肥(fei)等；還(huan)可用(yong)(yong)(yong)(yong)于(yu)制造其(qi)他化學品(pin)，如硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)硝酸(suan)(suan)(suan)鹽(yan)和硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)過氧化氫(qing)；也可用(yong)(yong)(yong)(yong)作(zuo)(zuo)蛋(dan)白(bai)質(zhi)的(de)(de)沉(chen)淀劑(ji)(ji)、萃取(qu)劑(ji)(ji)和燃料添加劑(ji)(ji)。醫藥領(ling)域：可用(yong)(yong)(yong)(yong)于(yu)制備一些，如的(de)(de)。生物(wu)(wu)學領(ling)域：多用(yong)(yong)(yong)(yong)于(yu)蛋(dan)白(bai)純化工藝方面，因(yin)為其(qi)屬(shu)于(yu)惰性(xing)物(wu)(wu)質(zhi)，不易與其(qi)他生物(wu)(wu)活(huo)性(xing)物(wu)(wu)質(zhi)發生反應，硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)是(shi)什(shen)么肥(fei)料，能(neng)較好地保護蛋(dan)白(bai)活(huo)性(xing)，且可形成高鹽(yan)環(huan)境，江蘇硫(liu)酸(suan)(suan)(suan)銨(an)(an)(an)(an)(an)，有利(li)于(yu)蛋(dan)白(bai)沉(chen)淀與后續的(de)(de)高鹽(yan)純化。

物理(li)性質：純品為(wei)無色(se)結晶或(huo)白色(se)顆粒，含(han)有雜質時(shi)(shi)(shi)顏色(se)可(ke)為(wei)微黃或(huo)灰色(se)。無氣味(wei)，相對密度(du) 1.77，折光率 1.521。在水(shui)中(zhong)的溶(rong)解度(du)為(wei) 0℃時(shi)(shi)(shi) 70.6，硫酸銨生產廠(chang)家，100℃時(shi)(shi)(shi) 103.8，不(bu)溶(rong)于乙醇和丙酮

化學(xue)性(xing)質：純(chun)硫酸銨水(shui)溶液(ye)呈酸性(xing)，0.1水(shui)溶液(ye)的為 5.5。常溫下性(xing)質穩定，但與堿性(xing)物(wu)質相(xiang)混(hun)時會(hui)分解釋放(fang)出氨。加熱到 513℃以上時會(hui)完全分解成(cheng)氨氣(qi)、氮氣(qi)、及(ji)水(shui)

硫酸(suan)銨(an)溶(rong)液呈酸(suan)性是由于其在(zai)(zai)水中發(fa)生(sheng)(sheng)水解反(fan)應(ying)(ying)，生(sheng)(sheng)成H+離(li)子(zi)。這種(zhong)(zhong)性質不(bu)僅(jin)在(zai)(zai)化(hua)學實驗中有重(zhong)要應(ying)(ying)用(yong)(yong)，也在(zai)(zai)農業(ye)生(sheng)(sheng)產中發(fa)揮著(zhu)重(zhong)要作用(yong)(yong)。了解硫酸(suan)銨(an)的酸(suan)堿性對于正(zheng)確使用(yong)(yong)這種(zhong)(zhong)化(hua)合物(wu)以及理(li)解其在(zai)(zai)不(bu)同領域(yu)中的應(ying)(ying)用(yong)(yong)具有重(zhong)要意義。

硫(liu)酸銨(an)，化(hua)學(xue)式為(NH?)?SO?，是一種廣(guang)泛使用的無機物。它通常呈現為白色結(jie)晶性(xing)粉末(mo)，無氣味，吸濕(shi)性(xing)小，不易結(jie)塊，便(bian)于(yu)儲存。硫(liu)酸銨(an)在(zai)水中的溶解(jie)性(xing)很好，性(xing)質穩定。
