Answer 1

CuSO4(aq)+2NaOH(aq)->Cu(OH)2(s)+Na2SO4
the ability of bases to release sodium ions into solution
the ability of bases to release hydrogen ions into solution
the ability of a base to react with carbonate or bicarbonate
the ability of a base to react with a soluble metal salt

In this reaction, the base (2NaOH) reacts with a soluble salt of the metal copper (Cu).
Base molecules have a specific ability to accept a hydrogen ion, usually from an acid or an acidic salt, but In this reaction, the base (2NaOH) reacts with a soluble salt of the metal copper (Cu).
