2NaOH+SO3=Na2SO4+H2O中Na2SO4沉淀吗

2NaOH+SO3=Na2SO4+H2O中Na2SO4沉淀吗 SO3+2NaOH=Na2SO4+H2O的反应类型是? 复分解反应有化合价变换吗 2NaOH+SO3=Na2SO4+H2O是复分解反应吗 SO3是啥啊 SO3+2NaOH=Na2SO4+H2O是啥意思 2NaOH+SO2=Na2SO3+ H2O ；2NaOH+SO3=Na2SO4+ H2O ；FeCl3+3NaOH=Fe H2SO4+2NAOH=NA2SO4+H2O 2NaOH+SO2==Na2CO3+H2O 2NaOH+SO3==Na2SO4+H2O 这两条方程式都对吗 2NaOH+SO2==Na2SO3+H2O和NaOH+SO3==H2O+Na2SO4这两个化学方程式怎么解释 H2SO4+2NAOH=NA2SO4+H2O 如何看出反应了 Na2Sx+NaClO+NaOH=Na2SO4+NaCl+H2O 2NaOH+H2SO4==Na2SO4+H2O H2SO4 +2NaOH==Na2SO4+H2O H2SO4 +2NaO 已知 H2SO4+2NaOH=Na2SO4+2H2O（Na2SO4中性,NaOH碱性）若稀H2SO4和NaOH溶液质量和
