In NaCl lattice structure if one of the sodium ion is removed from corner, the formula of the resulting compound is .....

Answer»

`Na_7Cl_(24)`
`NACL`
`NaCl_3`
`Na_3Cl_(11)`

Solution :Number of `NA^(+) ` ions = `(7 xx 1/8) = 7/8`
Number of `Cl^(-)` ions = `(6 xx 1/2) = 3`
`THEREFORE Na^(+) : Cl^(-) = 7/8 : 3 = 7 : 24`.
