acid sulfuros = H2SO3
raport atomic:
aven 2 at H la 1 at S la 3 at O
=> H : S : O = 2 : 1 : 3
raport masic
avem 2x1g H + 1x32g S + 3x16g O
=> H : S : O = 2 : 32 : 48 /:2 = 1 : 16 : 24
compozitie procentuala
avem 2x1g H + 1x32g S + 3x16g O = 82 g/mol
82g .............. 2g H ....... 32g S ....... 48g O
100%(g) ....... a% ............ b% ........... c%
= 2,44% = 39,02% = 58,54%
acid sulfuic = H2SO4
folosesti acelasi principiu ca mai sus....
acid sulfhidric = H2S
raport atomic:
aven 2 at H la 1 at S
=> H : S = 2 : 1
raport masic
avem 2x1g H + 1x32g S
=> H : S = 2 : 32/:2 = 1 : 16
compozitie procentuala
avem 2x1g H + 1x32g S = 34 g/mol
34g .............. 2g H ....... 32g S
100%(g) ....... a% ............ b%
= 5,88% = 94,12%
