- A is a sodium salt.
- B is an insoluble salt.
- C is a soluble salt of copper.
- D is a soluble salt of zinc.

Solution
- A is sodium salt it is prepared by neutralization of a base with acids.
\[\ce{NaOH + HCl -> NaCl + H2O}\] - B is an insoluble salt prepared by precipitation.
\[\ce{AgNO3 + HCl -> AgCl + HNO3}\] - C is a soluble salt of copper prepared by neutralisation.
\[\ce{Cu(OH)2 + H2SO4 -> CuSO4 + 2H2O}\] - D is a soluble salt of zinc prepared by simple displacement.
\[\ce{Zn + H2SO4 -> ZnSO4 + H2\uparrow}\]
