1)_Na2Sx+_NaClO+_NaOH=_Na2SO4+_NaCl+_H2O
Na2Sx+(1+3x)NaClO+(2x-2)NaOH=xNa2SO4+(1+3x)NaCl+(x-1)H2O
Sx2- 失去 2+6x 个电子 ,
ClO- 得到 2个电子
即 Na2Sx 系数为 1 NaClO 系数为 1+3x
那么 Na2SO4 系数为 x ,NaCl系数为 1+3x
根据Na守恒,NaOH 系数为 2x+1+3x -2-(1+3x)=2x-2
则根据H守恒 H2O 系数为 x-1
Na2Sx+(1+3x)NaClO+(2x-2)NaOH=xNa2SO4+(1+3x)NaCl+(x-1)H2O
