Best answer
`Cu(OH)_(2)` के लिए, `K_(sp)=[Cu^(2+)][OH^(-)]^(2)`
`pH=14` पर `[H^(+)]=10^(-14):.[OH^(-)]=10^(0)=1`
`:." "[Cu^(2+)]xx(10^(0))^(2)=10^(-19)`
`:." "[Cu^(2+)]=10^(-19)`
तथा `Cu^(2+)//Cu` युग्म के लिए
`E_(R.P)=E_(R.P.)^(@)+(0.059)/(2)"log"[Cu^(2+)]`
`E_(R.P.)=0.34+(0.059)/(2)"log"(1xx10^(-19))=-0.2205V`
