Question

21,2 g amestec echimolecular de alcool etilic si propilic se oxideaza cu o solutie de concentratie de 2 M de permanganat de potasiu in mediu acid sulfuric .Cantitatile de produsi organici rezultati prin oxidare sunt?

Answer 1

Amestec echimolecular => x:x
reamintesc: n=m/M => m=n*M
m etanol=46x (Metanol=46g/mol)
mpropanol=60x (Mpropanol=60g/mol)
mamestec=106x=21,2 => x=0,2 moli
1mol.................................60g
CH3-CH2-OH + 2[O] -> CH3-COOH + H2O
0,2moli.............................y=12g
1mol...................................74g
C2H5-CH2OH + 2[O] -> C2H5-COOH + H2O
0,2moli...............................z=14,8g
