Question

The reaction below demonstrates which characteristic of a base?

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

Answer 1

In the reaction of the type:
CuSO4(aq) + 2NaOH(aq) -> Cu(OH)2(s) + Na2SO4

Herein, base (NaOH) reacts with water soluble metal salt (CuSO4) to form metal hydroxide.

This displays ability of a base to react with a soluble metal salt. Hence correct answer is option D.

Answer 2

I think the correct answer from the choices listed above is the last option. The reaction below demonstrates a characteristic of base which is the ability of a base to react with a soluble metal salt. Hope this answers the question. Have a nice day.
