Question

запишите уравнения реакций:

H2SO4 + NaOH =

CO2 + NaOH =

CuSO4 + NaOH =

SO2 + NaOH =

Answer 1

H2SO4+NaOH=NaHSO4+H2O или

1                1

H2SO4+2NaOH=Na2SO4+2H2O

1                 2

 CO2+NaOH=NaHCO3 или

1           1

СO2+2NaOH=Na2CO3+H2O 

1             2

CuSO4+2NaOH=Cu(OH)2+Na2SO4

SO2+NaOH=NaHSO3 или

1           1

SO2+2NaOH=Na2SO3+H2O
