Concentrated borax solution + silver nitrate solution `to` Precipitate `underset("boiling")overset(H_(2)O)to `Produts(final)
A. `Ag_(3)BO_(3)`
B. `Ag_(2)O`
C. `H_(3)BO_(3)`
D. `AgBO_(2)`

Answer 1

Correct Answer - B::C
`B_(4)O_(7)^(2-) +4Ag^(+) +H_(2)O to 4AgBO_(2)darr ("white")+2H^(+)`
`2AgBO_(2) darr+ 3H_(2)O underset(Delta // H_(2)O)overset("Hydrolysis")to Ag_(2)Odarr ("brown") +2H_(3)BO_(3)`
