值急劇上升至因(yin)此能殺死一般生物體．起(qi)到消(xiao)毒殺菌的(de)(de)作用(yong)。 使用(yong)生石(shi)(shi)(shi)(shi)灰(hui)池塘中(zhong)(zhong)應(ying)用(yong)，是目(mu)前普遍(bian)的(de)(de)方(fang)法之因(yin)為石(shi)(shi)(shi)(shi)灰(hui)具有消(xiao)毒，水(shui)質調節(jie)的(de)(de)用(yong)途，成本低，既能發揮很好(hao)(hao)的(de)(de)效果(guo)。當然也(ye)有人使用(yong)漂，但成本要比石(shi)(shi)(shi)(shi)灰(hui)高兩倍(bei)，效果(guo)相當。熟石(shi)(shi)(shi)(shi)灰(hui)和(he)工(gong)業片(pian)堿(jian)(jian)(jian)(jian)（氫(qing)氧(yang)(yang)化(hua)鈉）都(dou)屬于強(qiang)堿(jian)(jian)(jian)(jian)性化(hua)學藥劑(ji)(ji)。在(zai)污(wu)(wu)水(shui)處理作為中(zhong)(zhong)和(he)時，它們可以相互替代。中(zhong)(zhong)和(he)效果(guo)差(cha)異不大(da)。熟石(shi)(shi)(shi)(shi)灰(hui)的(de)(de)堿(jian)(jian)(jian)(jian)度不低于氫(qing)氧(yang)(yang)化(hua)鈉，它所消(xiao)耗的(de)(de)酸要比氫(qing)氧(yang)(yang)化(hua)鈉高。 熟石(shi)(shi)(shi)(shi)灰(hui)與(yu)片(pian)堿(jian)(jian)(jian)(jian)在(zai)污(wu)(wu)水(shui)處理中(zhong)(zhong)的(de)(de)區別熟石(shi)(shi)(shi)(shi)灰(hui)與(yu)片(pian)堿(jian)(jian)(jian)(jian)污(wu)(wu)水(shui)處理從經濟上來說，片(pian)堿(jian)(jian)(jian)(jian)的(de)(de)價格是熟石(shi)(shi)(shi)(shi)灰(hui)價格的(de)(de)3倍(bei)以上，廢渣也(ye)比較多，溶(rong)解性沒有熟石(shi)(shi)(shi)(shi)灰(hui)好(hao)(hao)。熟石(shi)(shi)(shi)(shi)灰(hui)在(zai)酸性污(wu)(wu)水(shui)處理中(zhong)(zhong)除了作為堿(jian)(jian)(jian)(jian)性中(zhong)(zhong)和(he)劑(ji)(ji)外，其鈣(gai)離子還能與(yu)污(wu)(wu)水(shui)中(zhong)(zhong)的(de)(de)磷酸根(gen)離子產生氧(yang)(yang)化(hua)還原反應(ying)，生成磷酸根(gen)沉淀。達(da)到除磷效用(yong)。 熟石(shi)(shi)(shi)(shi)灰(hui)的(de)(de)堿(jian)(jian)(jian)(jian)性與(yu)工(gong)業級氫(qing)氧(yang)(yang)化(hua)鈣(gai)一樣。

工業級氫(qing)氧化鈣不(bu)能(neng)盛放(fang)在(zai)帶玻璃塞(sai)的(de)(de)(de)試劑(ji)(ji)瓶(ping)中，因(yin)為雖然二氧化硅化學性(xing)質穩定，但是會(hui)與強(qiang)堿反(fan)應(ying)(ying)，如(ru)NaOH，KOH，RbOH，Ba(OH)Ca(OH如(ru)果把氫(qing)氧化鈣放(fang)在(zai)帶玻璃塞(sai)的(de)(de)(de)試劑(ji)(ji)瓶(ping)中，會(hui)發(fa)生如(ru)下反(fan)應(ying)(ying)：Ca(OH)2+SiO2===CaSiO3↓+H2O。 而(er)硅酸鈣會(hui)沉淀在(zai)瓶(ping)塞(sai)上，導致瓶(ping)子打不(bu)開，所以不(bu)能(neng)盛放(fang)在(zai)帶玻璃塞(sai)的(de)(de)(de)試劑(ji)(ji)瓶(ping)中。⒒制取(qu)氫(qing)氧化鈣：H2O+CaO=Ca(OH)2（這里切(qie)記！沒有沉淀符號的(de)(de)(de)）⒓初中需掌握(wo)的(de)(de)(de)并不(bu)多(duo)：Ca(OH)2+CO2=CaCO3↓+H2O。 Ca(OH)2 + Na2CO3=2NaOH+CaCO3↓Ca(OH)2+2HCl=CaCl2+2H2OCa(OH)2+H2SO4=CaSO4+2H2O⒔氫(qing)氧化鈣還可以與 反(fan)應(ying)(ying)，生成漂白(bai)劑(ji)(ji)2Ca(OH)2+2Cl2=CaCl2+Ca(ClO)2+2H2O。
