The reaction below demonstrates which characteristic of a base? Upper C U upper S upper O subscript 4 (a q) plus 2 upper N a upper O upper H (a q) right arrow upper C u (upper O upper H) subscript 2 (s) plus upper N a subscript 2 upper S upper O subscript 4 (a q).

The ability of a base to react with a soluble metal salt

Explanation:

The equation is given as;

CuSO4(aq) + NaOH →  Cu(OH)2(s) + Na2SO4(aq)

A strong base (NaOH) can easily react with a soluble metal salt (CuSO4) and displace it.

The reaction between CuSO4 and NaOH is a double displacement reaction.

did anyone actually do this? like if anyone has submitted this i rly need .

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
