一:烧碱和硫酸反应的方程式
(1)2NaOH + H2SO4 == Na2SO4 + 2H2O
(2)AI(OH)3 + 3HCI == AICI3 + 3H2O
(3)CaO +攻H2O == Ca(OH)2 ----酚酞变红!
二:氢氧化钠与硫酸反应方程式
NaOH过量时:H2SO4+ 2NaOH= Na2SO4 +2H2O
NaOH少量时:H2SO4+ NaOH= NaHSO4 +H2O
(1)2NaOH + H2SO4 == Na2SO4 + 2H2O
(2)AI(OH)3 + 3HCI == AICI3 + 3H2O
(3)CaO +攻H2O == Ca(OH)2 ----酚酞变红!
NaOH过量时:H2SO4+ 2NaOH= Na2SO4 +2H2O
NaOH少量时:H2SO4+ NaOH= NaHSO4 +H2O
