Sodium hydroxide interacts with the following of the listed substances: copper (II) sulfate, magnesium chloride

Sodium hydroxide interacts with the following of the listed substances: copper (II) sulfate, magnesium chloride, copper (II) oxide, sulfur (IV) oxide, potassium sulfate, nitric acid, ammonium chloride. Write down the answer in formulas. Draw up possible molecular and ionic reaction equations.

CuSO4, MgCl2, SO2, HNO3, NH4Cl.

1) 2NaOH+CuSO4–>Cu(OH)2+Na2SO4
2Na+ +2OH- +Cu2+ +SO4 2- =Cu(OH)2+2Na+ +SO4 2-
2OH- +Cu2+ =Cu(OH)2

2) 2NaOH+MgCl2=Mg(OH)2+2NaCl
2Na+ +2OH- +Mg2+ +2Cl- = Mg(OH)2+2Na+ +2Cl-
2OH- +Mg2+ =Mg(OH)2

3) NaOH+HNO3=NaNO3+H2O
Na+ +OH- +NO3- +H+ =Na+ +NO3- +H2O
OH- +H+ =H2O

4) NaOH+NH4Cl=NaCl+NH3+H2O
NH4+ +Cl- +Na+ +OH- =Na+ +Cl- +NH3+H2O
NH4+ +OH- =NH3+H2O
