Question

Find the charge and stock name of each formula.

Sn1O3
( Sn1O2.5 ) Sn2O5
Sn1O2, stannic oxide
( Sn1O1.5 ) Sn2O3
Sn1O1
( Sn1O0.5 ) Sn2O1

Answer 1

Sn can have +2 or +4 and O -2 oxidation state. the most common for Sn is +4
for the ions I don't know the names here are the charges

SnO3 (+4) + 3(-2)= -2
(+2) + 3(-2) = -4
Sn2O5 (+4) 2 + 5 (-2) = -2
(+2) 2+ 5(-2) = -6
SnO2 (+4)+ 2 (-2) = 0 Tin (IV) oxide
(+2) + 2(-2) = +4
Sn2O3 (+4) 2 + 3 (-2) = +2
(+2) 2+ 3(-2) = -2
SnO (+4) + (-2) = +2
(+2) + (-2) = 0 Tin (II) oxide
Sn2O (+4) 2 + (-2) = +6
(+2) 2+ (-2) = +2
